This is excellent. Thank you. 

Now I understand the system much better.  

Will let you know if any of the screws are loose etc. Other than that I believe that your suggestion will resolve the issue.  The system has worked flawlessly since last evening.  Being naturally lazy at least with the outside temperature where it is I'm hoping not to have to troubleshoot till the weather cooperates a bit more!  

Once again thanks for your wisdom and willingness to share Much appreciated 

Thanks will try that.

The water heater should not be on the inverter. However, who knows who or what modifications may have been done. It should be very easy to determine by simply finding the (likely 30 amp breaker), that feeds the inverter. Turning it off will disable the inverter/converter but you should still have power to the water heater assuming you are on 50 amps or the generator is running. 

I will assume you have a Magnum 2012 or the pure sine wave one for argument.

As mentioned, two separate output paths from one input (30 amp) path. Those small breakers on the inverter/charger can fail, or you could have an overload on one of them.

One path goes to the microwave, and the other to some less hungry circuits. 

I'm not sure what a (rebuild) would have entailed other than an inspection and cleaning. 

The one path that is failing could be a bad connection on the actual breaker inside the Magnum as I found on mine. 

IF you are comfortable with 110 volts and a meter, you could probably disconnect the two output hots, then move the wire on the breaker that is popping to the other location. There is a simple tie down board on the inverter and you do not have to take it apart, but you do have to remove input power of course. 

If that breaker now pops, you have some sort of load that is too large, and if the water heater is on that leg by design or accident, that could be an issue. 

I suspect this problem just came up so the likelihood of the water heater being on that circuit is minimal. 

Great suggestion.  Will try this out.  Much appreciated

Your GFCI outlet (usually in the bathroom) isn't tripping?

GFCI has not tripped. Thanks for the suggestion. 

Thank you very much, Tom.  Most helpful.

We did run the generator with the same result. The same results when we switched to solar.

I have verified that the pedestal is providing power.  The Surge suppression system advises that there is power on both legs, 120 volts on line 1 and 122 volts on line 2.  Line 1 draws 6 amps, line 2 is zero (when the number 1 pin breaker on the inverter is tripped)

The ATS is NOT the original one.  We replaced it with another 3 years ago.  I can't find/remember the name of the manufacturer/model of the replacement, but at the time, it was deemed to be the best-performing ATS for RVs and yachts.  I agree fully with you about how dangerous the original one was.  Ours failed, and when the cover was pulled off, the inside was totally burnt.  You could smell the burnt wires and melted cabinet! ANYONE with the original ATS owes it to themselves to replace the ATS as soon as possible.

At the electrical panel, I have similar voltages (to the exterior measurements at the surge suppression system) on either side of the main breaker when measured individually.  One interesting thing is that I have a combined voltage of approximately 240 volts when measured individually, when I measure the voltage across both sides of the main breaker, I get 207 volts.  I don't understand that, but that's a whole different concern now.

When the pin on the inverter is tripped, the fridge, washer/dryer worked fine.  However, all other outlets and the microwave have no voltage.  

Once I reset the first pin breaker on the ATS everything works perfectly.  But 10 minutes later it tripped again.  I then reset the pin breaker again, took the water heater off 120 and placed it on 12 volts, and all has been fine since.  My thinking is that there is too much load on the one side.  Does that make sense?

One other item that may be a factor is that when we purchased the coach, the inverter had to be sent back to the manufacturer for repair or replacement.  It was repaired and since we have not had an issue.

I hope this provides a better understanding of my situation

Thanks again for your assistance, much appreciated.

Based on what has been posted.....These are my assumptions

You have a Magnum Inverter per the Manual.  There are THREE Circuit Breakers....these are Pin Style. One is a 30 Amp INCOMING power.  TWO are 20 Amp Outgoing power.  ONE line goes to the INTERNAL Receptacles, through a GFCI. The OTHER line goes directly to the Microwave. HOWEVER....The wording of your post is confusing....so this needs to be responded to so we can help.

IF you have 115 VAC on the Internal Receptacles and the Microwave, then you MAY (Probably?) meant that you have lost LINE 1 ON THE MAIN PANEL.   Let me explain.... There are TWO lines (1 and 2) on the Main Panel.  The AC  GOES DIRECTLY from CG Pedestal via the Shore cord to the  AUTOMATIC TRANSFER SWITCH (ATS). Your MH came with an IOTA 50-R Automatic Transfer Switch. These ATS are a hazard.  They can catch fire and also cause electrical shorts.

PLEASE refer to Page 163 of your Owner's Manual. This is the PICTURE of the Inverter. NAVISTAR recalled and replaced all of these.  BUT, since, like me, your MH was made by the ORIGINAL Monaco company and NOT Navistar, then the "LIABILITY" for Monaco's issues did NOT cover your MH. It is an ORPHAN.

There are TWO INCOMING LINES.  They come through the shore cord. If you read Section 8 of the manual, it explains it. A 50 A Pedestal has a Dual Pole 50 Amp Breaker. There are FOUR wires inside the Shore Cable. One is Black and one is Red. These are Line 1 and Line 2 HOT. There is a WHITE Neutral. There is also  GREEN Ground. You have LOST Line 1 at the MAIN PANEL. There are many places where that can HAPPEN.

The Pedestal receptacle can be defective... The CG can verify that for you.

Your 50 A shore (Male) Plug is NOT INDESTRUCTABLE. Mine failed. It can be replaced with a Camco 50 A RV plug that Amazon sells. This is NOT a complex job. Anyon with electrical knowledge or a residential Electrician can do this. it is NOT something that requires an RV Tech.

There is a Junction Box that connects the LINE (SHore Cord) to the INTERNAL Cable that goes to the ATS.

The ATS can be bad.  In your case, if you STILL have the ORIGINAL IOTA-50R, it needs to be replace IMMEDIATELY. The most popular one is an ESCO or LYGHT 50BRD. I will attach a "Search Results" on the IOTA.  This search has many topics and discussion of replacing the IOTA. It can NOT be stressed enough that his is a fire and personal safety issue and needs to be replaced immediately.

YOU CAN TRY to run the Generator....but sometimes the IOTA will work on one source (Shore or Genny) and NOT on the other.

NOW, if the ATS has been replaced, the next step is to unplug the SHORE and start the Generator. IF you have BOTH Line 1 and Line 2, then there is a problem with the SHORE system....again....follow the above.

I am editing the TITLE as your comment about what is GONE does NOT impact or come through the INVETER.

Typically, the Inverter on a Monaco is on LINE 2....so if you have INTERNAL power (receptacles and microwave), then the INVERTER is working fine.

Please clarify if you mean that you lost MAIN POWER or LINE 1 on the MAIN PANEL....OR if you mean one of the OUTPUT lines on the INVERTER. Look on page 168.  This is the MAIN PANEL.  The AC comes in here. Notice that Line 2, as I suspected, has the 30 Amp Breaker. 

NOW if you mean that you have NO POWER to the FRONT AC or the WATER Heater (or Fireplace option if you have that), then this is a MAIN POWER ISSUE...and NOT an Inverter issue.

If it IS the inverter, then push in the TWO 20 A (may be 15 A) pin circuit breakers on the inverter. They are visible and look like "plastic pins or switches".  If you reset the INVERTER by holding in the POWER BUTTON for 20 seconds (Soft Reset) and all was well and DID NOT have to reset or push in the Circuit breakers....then that is a totally different problem....

It is important to KNOW which power you have lost....so please post....

Hope this helps....

The Inverter has (MOST LIKELY) three (3) Pin Style Circuit Breakers. If you did a SOFT reset of the Inverter and all was well and then you have lost either the internal receptacles or the Microwave....that is Line 1 and Lin3 2.  Without knowing how Monaco wired it up....then it is difficult to say which Line is which. 

SO....exactly what power do you NOT have.  FWIW, there is an Automatic Transfer Switch inside the Magnum.  It is a relay on the MAIN (Control) board. It works this way. When the Inverter can sense or "measure" voltage on the incoming LINE (from the Main Panel). Once the Inverter "sees or senses" the power and has a "functional or good" battery bank, the Inverter then PASSES the power to the TWO CIRCUITS (Internal Receptacles and Microwave). IF you mean that the receptacles or microwave is DEAD, then that IS an Inverter problem...and the ATS can NOT be repaired....it requires a NEW Control Board....

Please give us MORE INFORMATION.  Thanks....

No auxiliary heating being used….ever. 
 

Unit is plugged in to shore power. 

We have a 2009 Monaco Knight PKQ38 and have lost the #1 leg of power off of the inverter.  Had the whole inverter rebuilt when we purchased the coach in 2020 and have not had any isses since. 

Tonight is the coldest night of the season (of course!) and suddenly we lost one side/leg of the power.  We reset the inverter and everything was fine then 10 minutes later it happened again.  

Any words of wisdom would be warmly received and much appreciated. 

Thanks Laurice

Thanks all. Much appreciated 

Great response.  Thank you so much. 

Thanks all. Great information and confirmed was I thinking.  
we are full timers in southern BC so it can get a little col in the winter but based on your advise, we’ll venture out and throw the main break going forward.

Many thanks for the info. Much appreciated 

Quick question. Can I exercise my generator while on shore power?  I just replaced the automatic transfer switch and not sure if the exercising was the cause or nearly a coincidence. Thanks in advance

Do you have rear slides and do they work?  Several years ago I had the same problem and I called Monaco (back when you could get help on older models)  There is a 5 amp fuse in my battery bay that had blown.  The signal from my control for the slides goes through this fuse.  I had a 09 Knight DFT so maybe that could be your problem.

Do what Jim has posted. Check that fuse to make sure its good. I totally forgot about that.

Thanks Gary. Checked all fuses. All good.  

Thanks for the info. Appears that we have a different system than outlined in the manual. We do not have a rack and pinion system. 
 

Dave P.  You’re right exact same situation. Unfortunately ( in this situation) we are full timers.  Would love to get galley slide out. 
 

Thanks for the info. 
Laurice

The front slides on our 2009 Monaco Knight 38PKQ have stopped working. There is power to the motor.  It appears that the seal between the pump and the motor failed as there is now oil visible when the dust cap on the end of the motor is removed. I understand there is a minimum 2 weeks to get a motor/pump assembly from Lippert. Galley slide is in, living room slide is out. 
Questions:

1) Can/how do I extend the galley slide?  How specifically do I do this?  I have identified the hydraulic line (labelled orange/black) I believe the valve is located behind the solenoid.  Which way do I turn the valve to extend the slide? Which way do I ‘spin’ the motor?

2) Once extended will I be able to retract? Or is this a one time action to allow transport to a dealer for replacement?

Any help would be most appreciated

Still have old unit. 

Thanks.  Really appreciated.  Will check it out.

Thanks.  Will try and find.

Good idea.  Too bad there is nothing available for 12V configurations.

I am looking to find a 7 day 24 hour timer to control the on/off function of our water heater and timers to be able to set different temperatures for the furnaces and air conditioners.  I am looking for a system similar to the options available for a sticks and bricks heating / air conditioning systems.  The heating/ac system in our coach is controlled through a Carrier IV wireless remote.  Has anyone found a way to do this in their coach?

Thanks

Any screws going in from the sides, or down from above?

None whatsoever  

 None whatsoever.  Only 2 long bolts from below.  

Thanks.  Got it out just fine.  All good. No damage 

thanks 

We like it too. Owners here are getting a little long in the tooth and at times challenged to keep up. But overall still a nice place to call our base.  Any thoughts on visiting again?

Thanks all.  I had done a search before I started and did not realize that the two long bolts actually were accessed behind the filters.  (I know it said that, but....) I was looking for the bolts from the top...   I know.  Sure hope my wife doesn’t read this post!

thanks all. 
 

now for the challenge of installing the new one .... without the two long bolts and without an upper cabinet.  

We need to replace the OTR Sharp Carousel convection microwave in our 2009 Monaco Knight PKQ38. 
Does anyone know how to remove this?  I have removed the ‘cup rack’ from above the unit and I see there is a piece of plywood that has been installed but cannot see any screws attaching the microwave to it. Perhaps it is just a spacer?  But there has to be some point that secures the microwave so it does not pivot forward on the bottom mounting plate. I have removed the fan assembly on the top but still cannot find any attachment point. 
 

Has anyone replaced their microwave in a similar rig?  Sure would appreciate some guidance. Thanks
