Update: I received a new motor pump assembly yesterday and installed it today. It think that fixed the problem. The first thing I did was test it without turning the water on and the motor ran. This is something I could not get the old one to do consistently. So I hope all is well, I know my wife is happy not having to walk to the activity hall to use the facilities where we are spending the winter. I received a new control module today. I’m going to hold on to it for a couple of weeks then return it if things keep working. Crossing my fingers. Thanks for all the great advise and suggestions.

Thanks, Myron Very good suggestions. I’m going to see if I can figure it out with your guidelines. I have a new motor and control board coming today and tomorrow. If I don’t need them they can be returned.

My Thetford Tecma macerating toilet has stopped working three times in the last month. Each time I completely pull the toilet, disassemble it and open up the macerating pump. Quite a big messy and gross job. Each time a find a small amount of solids (you get the picture) in the fins of the pump that were not macerated. After clearing this and reassembling everything it works just fine for a couple of weeks until it happens again and I have another half day job ahead of me. This morning it happened again and I cleared it in 10 minutes. In the past during reassemble I have always check all the electrical connections and connected the pump motor to 12 volts, with my knock off power prob, to make sure the motor was operating. This time I thought before pulling the toilet I would try to reach behind, unplug the pump from the control board (black and brown wire plug) and connect my power prob to the motor with it in place. This is a DC motor that will run in either direction. When I connected power and ground the same way as the plug the motor would not operate but when I reversed polarity it ran and cleared the obstruction. I then went back and forth a couple of more times and decided it ran works for now. I’m thinking about replacing the macerater motor/pump assembly since it obviously not working as it should. This is a real dilemma. This is the only toilet in our MH. it’s 15 years old, replacement or replacement parts are hard to come by. Not sure how the make another brand macerater toilet electronics work, if I want to spend $1500. Can not use a standard bottom dump because we are not on over the black tank. Advice, ideas or suggestions would be welcomed. 2009 Holiday Rambler Ambassador 41SKQ Tecma model #36311
