Viking 4 burner gas range

when the lp conversion is done , it is normally just a jet size change that is done
however the air shroud has to also be adjusted to get a clean blue burn of the flame
The just jet change results in a slightly yellow flame which is incomplete burn of the gas and that creates carbon build up at the jet and burners causing partial blockage
I would suggest that you call in an accredited gas fitter to check the problem and if necessary , clean the jets and adjust the air shroud

On the back of the stove are 2 blower fans just under the cooktop. They are cooling fans to keep the controls from overheating. They are a long tube type fan and are left and right side. My guess is one or both are not coming on. They are controlled by a round disk temp control also under the cooktop. At a preset temp these fans should come on and keep all the control area cool enough to stop any damage. The fans need tested and maybe the temp control needs replaced.

Can you post more details like: Does the oven ignitor come on (glow orange)? Can you hear the oven gas valve click open and/or smell gas? Do all the stovetop burners work fine? Have you checked your propane tank to be sure you are not out of gas?

If the broiler burner is the only burner, then it should come on. If there are two burners, chances are the broiler burner comes on to get the oven heated up more quickly. Once near temperature, the other burner maintains temperature.

Check your owner manual to confirm.

This happened to my DCS when the Hot Wire Relay went out. It isn't an expensive part, but finding someone that knows what needs to be replaced, and then can replace it is hard. My oven also did the opposite and continued to heat without shutting off, and it was once again the hot wire relay.

I have a Frigidaire Model Number GLGF377ASF. The stovetop burners work just fine but the oven and broiler do not work.

Igniters need to be replaced

Gas oven does not work. Burners and broiler work. When oven kGnob is turned on, there is no glow at ignitor, nor any gas smell.

Please follow this LINK for your manual

Have to check if there is power at the oven & broiler first.Maybe a bad thermostat located in back of oven wall.
