Oven Problem

I have 4-burner Magic Chef stove/ oven in my 85 Sovereign. The oven has a pilot which is manually lit. When I liight the pilot, I get a very small flame that isn't long enough to reach the thermocouple. Consequently, the oven won't light. Thinking the pilot might be clogged, I removed it for cleaning. While it was out, I lit the propane coming out of the tube that supplies the pilot. To my surprise, I get the same tiny flame from the supply tube without the pilot installed. The burners on the stove work fine, so I know propane is getting to the stove.

The oven on this trailer has rarely been used and worked ok the last time it was used (about 4 yrs ago).

Any suggestions for troubleshooting this problem?

safety valve

Not sure this appliies but when I purchased my 310 mh, the pilot lite flared up dangerously. Dealer put a safety valve in before the new pilot valve that limited gas pressure in case of pilot valve light failure. I can't see it just looking in the oven....maybe a po or factory did the same to yours....I understand they are pretty much a standard feature on newer units....lol...jem

Alan,

You may just be better off having a qualified LP tech look into this for you.

LP gas is one of those items that I feel for safety reason, a qualified LP tech is well worth the money.

Not sure if you've got the same model but mine has a pilot adjustment screw behind the knob.it's a small brass screw and they break if you're not careful. Mine has the screwdriver slot shutoff as well up top as there is no safety shutoff on the oven thermocouple.

Oven

Rats, I don't seem to have the pilot adjustment screw. That would certainly have made matters easier. Mine has a flat plate on the back of the oven valve, but otherwise nothing other than mounting screws.

Thanks.

Is your constant pilot staying lit? If so when the oven calls for heat there is an increase in gas supply in the pilot line causing the
flame to envelop the temperature response unit, which in turn turns on the main gas valve to the main burner, making it light. There are two different oven thermostats, one with an adjustable pilot and one without. Looks like you have one without.

Confusing, huh? I would fax you over whatever literature and tech stuff I have on my drop in cooktop but since mine is different maybe it won't help? I have a 74 with separate oven and cooktop. Let me know?

Oven

Well, after further examination, I realized the pilot control is "behind" the knob (as in remove the knob to get access). It is set for the maximum pilot. After fussing some more with the oven control, I found that sometimes turning the knob to the maximum temperature setting and pushing on the knob, the pilot flame size would increase to the point that the main burner would ignite. The main burner comes on for a few minutes and then goes out. At that point, the pilot has dropped back to a minimum flame. Pushing and turning the oven temperature knob affects the pilot size but sporadically.

I am beginning to think that the problem lies with the oven temp valve which supplies both the pilot and main burner.

Alen:
I have exact same AS, Sovereign 85, and the same kind of oven. I have the same problem. I did find the pilot control screw and it is at its max, just like yours. When I wiggle the control knob, the secondary pilot flame increases. But that is it. The main oven burner does not come on. Could you tell me what did you finally do about the problem with your oven?
thanks
