Hello, hopefully the pros on this site can help me do some troubleshooting. The infrared broiler unit on my 6 year old Thermador professional gas range (liq. propane) has stopped working. The igniter unit glows brightly orange, but the mesh screens do not ignite. If it matters, when I turn the broiler on I don’t hear the gas flowing, as I do when I turn the oven on.
The broiler on this range has always been a little funky. In the past, after using the broiler (not used very frequently) we have what can only be described as a “mini” explosion in the closed oven a minute or so after we turn the broiler off. Definitely unnerving.
The burners and over all seem to be working fine.
Did you replace the burner orifice when you convert the range to LP? It must be replaced and I did not find the conversion kit in the parts list for this model. According to the manufacturer instructions this range is not convertible and the type of gas (natural or propane) should be specified at time of purchase.
Also I would recommend to inspect the broil burner for any damages, like a burned through holes.
Hi Gene, and thanks for the reply.
The oven was in our house when we purchased it, so I can’t be absolutly certain about the LP conversion. But except for the broiler, all other functions of this range perform as you would expect them to. If the conversion wasn’t performed properly, do you think I would have been seeing other problems?
When I turn the broiler on, the broiler igniter is glowing brightly after about 15-20 seconds. Does it perform some other function? Should this igniter be giving off any heat that I could feel by putting my hand near it?
Also, when I turn the oven thermostat on to any temperature, I can hear the sound of gas flowing–which is normal. When I turn the knob to the broil setting, should I still be hearing gas flowing?
