Customer Question

I had my Dometic, Model 66E plugged into electric and it was functioning. I checked it today it was not working at all. I tried to light the propane, but when I let go of pilot light, it goes out.
Is there some unit I can change to make both modes work again?

That is a pretty old unit.........but, there should be parts available still. Some testing would need to be done to find out what parts it needs. Sounds like maybe a thermocouple and a heating element. I am attaching a link to the Dometic Service Manual which covers this unit. Print out a copy as there is some good information in there. I just repaired an RM53 this week in my shop and it is working great! Let me know if you need help with the testing. Don't forget to have the LP pressure checked at the tank regulator as that can affect the LP side. If the pressure is too low the thermocouple may not get hot enough to keep the gas valve open. Hope this proves helpful here. Please get back to me if we need to dig deeper into this as all follow ups are included in our fee.
