A thermocouple is a device used to measure temperatures in a variety of ways. It has two junctions, one of which is exposed to the temperature to be measured while the other is kept at a known reference temperature. If you need to bypass a thermocouple, there are a few steps you can take to do so.
The first step to bypassing a thermocouple is to disconnect the two junctions from each other. This can be done using a pair of insulated wire cutters. Cut the two wires, being sure to cut each of them at the same length. This will ensure that the two junctions will not be connected to each other.
The next step is to connect the two junctions to a dummy thermocouple. This is usually done using a pair of insulated alligator clips, one attached to each of the two junctions. Make sure that the clips are securely attached to each of the junctions, and that they are not touching each other.
Once the alligator clips are attached, connect the dummy thermocouple to a power source. This can be done using a set of insulated jumpers. Be sure to connect the correct polarity, as reversing the polarity can cause damage to the thermocouple. Once connected, the dummy thermocouple should be able to emulate the temperature of the original thermocouple.
Finally, the dummy thermocouple should be connected to the control system. This can be done using a set of insulated jumpers. Connect the dummy thermocouple to the appropriate input on the control system, and the system should now be able to read the temperature of the dummy thermocouple instead of the original thermocouple.
Bypassing a thermocouple is a relatively simple process, and can be completed in a few simple steps. Disconnect the two junctions from each other, connect the two junctions to a dummy thermocouple, connect the dummy thermocouple to a power source, and finally connect the dummy thermocouple to the control system. Following these steps should allow you to successfully bypass the thermocouple.
How to bypass your thermocouple on a propane heater
I get tired of all the safety equipment because it causes more problems for me than fixes. I have bypassed the thermocouple switch so you don't have to hold the pilot down to ignite the system. All to your equipment at your own risk. This makes it far more dangerous but with far less breakdown problems
