Like so many I have a little time on my hands so I’m delving into an issue that isn’t very important in my RVing but would like to know if it works. I have a wet bay heater that I’ve never seen give an indication of it working by the light next to the On/Off switch. I don’t really know if I’ve ever been in a situation where would have come but have always left the switch in the on position. I located the heater in the bay and found It has three wires leading to it, black, red and white. Can anyone tell me what each wire is? I assume one is power for the heating element, one for the fan and one the ground. Or is one power and each of the other two grounds?
I understand there should be a snap disc thermo switch but I can’t find anything like that in the bay. The three wires mentioned above come out of a wire bundle tube that comes out of the ceiling of the bay. Where should I look for the snap disc?
I have read on other forum threads there is an internal fuse In the heater that is subject to burning and can’t be replaced. However, that thread described a means of putting another fuse in the power line, externally I believe. The problem is the heater will be very difficult to remove. It sits behind two drain pipes, fresh water and gray. Looks like one will have to be removed to get the heater out. Not a job for me.
Any suggestions on my project?
Thanks
