I have a 1988 Terry by Fleetwood and I’ve tried replacing the thermocoupler but the pilot light still doesn’t stay lit and I’ve heard that I would have to replace the gas control valve then. Anyone know where I can find a replacement for a Atwood gas control valve MPD-91043?

Often times a bit of wind would suck the pilot light out, on older models. Using a tooth pick stuck in one side of heater door, would help eliminate this problem. It would allow air to pass through, keeping the pilot lit.Not what your asking, but I can't help, as to finding the replacement.Jerry

Are you getting propane to the other appliances? Check range for good clean blue flame.You could have a bad regulator.Replacement

Yep enblethen I have propane to everywhere else and the pilot light for the water heater, I did get the main burner to ignite for a second but that was only one time and couldn’t get the same result

Have you cleaned the burner tube and orifice in the propane valve?Was the range burners bright blue flame?

Yes everything is clean, it seems like if I play with the switch, sometimes it acts like there some gas there. This might sound stupid but are there actually any electrical wires hooked up to it? I can see any wires from the outside

25-30 Millivolts is what thermal couple puts out. What is lowest voltage scale on your meter? Should have a millivolt scale.
Look at the valve end of the thermal couple to show where to touch in valve. It is very close to opening.

Stupid me, I over looked that the 200m on my volt meter for some reason but it’s running anywhere between 23-26MV. I tried to ohm test the valve again but I don’t think I’m able to reach far enough inside to hit the contact, it feels like I’m only touching threads or the ohm part isn’t working on my meter

Tomorrow I’ll get some wire to put into the coupler valve port and see if I can get a ohm reading
