What is a thermocouple


A Thermocouple is a sensor used to measure temperature. Thermocouples consist of two wire legs made from different metals. The wires legs are welded together at one end, creating a junction. This junction is where the temperature is measured. When the junction experiences a change in temperature, a voltage is created.

Small burner will not stay lit when it sparks


assuming this is a gas cooktop? It would be part of the flame failure safety most likely. There is a thermocouple that detects the flame and converts that heat to a small electric signal to tell the gas valve to stay open and/or closed.

A thermocouple is a sensor for measuring temperature. It consists of two dissimilar metal wires, joined at one end.
In the event the flame goes out, the design of the thermocouple is the valve would shut of gas supply to the burner.

In the event the thermocouple is faulty, check it is clean from carbon, and ensure it has not been bent.

Contact a qualified technician to get them to inspect further and replace thermocouple if required.

Model wfs1273aw. What is the operating range of the thermocouple (ohms) in the heating element unit?


Hi Trevor

I guess it's open circuit so you can't measure it.

Does the thermocouple not have a part number on it?

I'll be surprised if anyone can provide an answer to this!

I take it that the thermocouple cuts the juice off to the element when it reaches a certain temperature. Or is it just stops the element from overheating?
Good Luck
Cheers
I'm Trevor also

Pilot light and heater will not stay lit


If the pilot light won't remain lit after you release pilot button you will need to replace the thermocouple. If you do not know how to do this it is generally a fairly easy job. First locate lines going from gas valve into burner compartment. There should be three, one to pilot light one to main burner and one to thermocouple. The thermocouple line is usually copper color and mounts directly in front of the pilot light. They usually slip into a friction fit holder so you disconnect line from gas valve and pull gently on line to remove. Measure length and get a new thermocouple at most hardware stores. If you can reuse the old holder then install thermocouple by inserting it into holder and seating it as far forwards as it will go. If you damage holder on removal there should be a new one with new thermocouple. Try to center thermocouple in pilot flame. Reconnect to gas valve and light according to instructions. I hope this helps you. Thanks

How to fix F7 in turbochef


F7: Thermocouple Open

CC Thermocouple

Reads 999?F/C or

IR Thermocouple
Reads 1999?F/C



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.

Two Gas hob burners will not remain alight


Does The thermocouple NOT hold at all or does it go out on low ? make sure the Flame heats the thermocouple , have you tried of disconnecting the Thermocouple from the Magnet and just clean the terminal on the T/C Have you measured the T/C Millivolt reading ? Have you got a clean connection on the Electromagnet ,Chech for bad solder joint in the Magnet
