I am having trouble with the Furrion Oven/Range Model FSRE17SA-BL originally installed in my 2020 Grand Design 2670MK. Stove has worked in the past. Right now, however, I push in the knob and light the pilot. It lights. I hold it for a long time and release the knob and the pilot should remain lit. It goes out. If I light up the oven while holding the knob in to keep the pilot lit, the burner lights up normally. When I release pressure on the knob, the pilot goes out as well as the burner. I think the thermocouple is operating correctly - output voltage increases from 0 to 15mV when you put a match to it. I took the thermocouple connection to the control valve apart and held it in contact by hand to make sure the control valve was getting the signal. Same result. I believe the issue is the control valve. I have seen discussions about this stove and Furrion getting some bad control valves so not sure if that is it or not. I do know they have changed the design and are not providing control valve parts/support for this 2 year old model. When I called Furrion they said I had to replace the stove. Suggestions on repairing/replacing the gas control valve or other troubleshooting tips?
