How to replace the thermocouple on belling G756 oven

Hello Peter;

My name is Peter. I am a retired field service appliance technician.

I recently repaired a oven that would be off as much as 200 degrees. The normal operation of your oven is to rise 20-40 degrees above set temperature and shut down until it drops 20-40 degrees below set temperature, turns back on and repeats the cycle again.

Generally, there are only three components that control your oven temperature:

1.) The Heating Element - If you are getting heat your heating element may be good. To be on the safe side inspect the two connections on the back wall to ensure they are not corroded.

2.) The Thermocouple - There are several different thermocouples depending on your model and if your have gas or electric. These are easily replaced.

3.) Oven Control - Here again there are several different controls, both mechanical or digital.

I just purchased a oven thermocouple and a reconditioned digital control over the internet for under $75.00.

IF YOU HAVE A DITIGAL CONTROL - GROUND YOURSELF BY TOUCHING BARE METAL. STATIC ELECTRICITY WILL KNOCK OUT A BOARD.

So, go into the following website put in your model number and select parts. Several diagrams with part numbers will appear. Your model number is on a metal plate on the face of your oven after you open the door.
Fine your thermocouple and oven control. Copy these part numbers and search the internet for best price.
First, replace the thermocouple. If this solves your problem then return the control for credit if not install the oven control. The highest probably is you have a bad thermocouple

I believe you mean a thermostat. Contact a distributor such as Automatic Appliance Parts at 800.323.0270

The thermocouple is faulty. This needs to be replaced by a registered gas safe engineer

Try replacing just the thermocouple. You don't say how old the oven is, but the thermocouple is the device inside the oven that takes a beating (especially if it is a self clean model) and needs to be replaced every few years. A failing thermocouple allows wide temperature fluctuations.

1. Check the connection of open thermocouple on the I/O control board.

If the connection is OK, verify thermocouple is not an open circuit

by using your ohm meter. The cook cavity thermocouple should

measure approximately 4-5 ohms and the IR thermocouple should

measure approximately 30-40 ohms. Measure at the I/O control board

40-pin connector.

o Thermocouple indicates open circuit: Replace defective thermocouple.
o Thermocouple OK: Replace the I/O control board.

My Kenmore electric wall oven will not increase the heat to the desired setting. The electronic display holds at 100 degrees. Could the problem be the thermocouple or the electronic range control. The range control is hard to find, which is part # 318010701, made by Fridgidaire.

the flame failure device has failed ,you will need a new thermocouple

Possible a bad thermocouple, could also be bad gas pressure to the unit, my bet would be a thermocouple.
You should be able to replace this on your own, if you see where the pilot flame is, you will see the thermocouple that sticks into the flame, it may have fallen off or may need replacing, it should lead back to the gas valve and should be replaceable.
Grainger normally stock a lot of thermocouples and could even cross reference one for you.

Look at the bottom of the oven and see if you can remove the panel, if its all one piece then take out broiler pan and look inside to see if you acan get to the pilot burner. Good Luck
