WebJun 28, 2012 · The Robertshaw 1980-036 Snap-Fit Thermocouple ensures an operative standing pilot light so the main burner gas properly ignites upon a call for heat. Also, it is placed in gas applications to detect a flame and shut off the potential gas flow to a burner. This gas thermocouple has a stainless steel outer jacket for long life and resistance to ... WebReplacing a thermocouple becomes necessary when the pilot light won’t stay lit even after the old thermocouple has been cleaned. Choose the new thermocouple based on the size and mounting style of the old one. Commercial thermocouples range in size from 18-48 inches and are interchangeable. Universal thermocouples have millivolt rating of 25-35 mV.

WebOct 26, 2024 · The thermocouple needs to heat up for 30 seconds to 1 minute in order to obtain a proper reading. The desired reading is 30 millivolts, with a swing of +/- 5 millivolts. If the readings are in that range, and you have been having pilot failure issues, there is more than likely some other cause. WebAttempt to relight the pilot light. Once you light the pilot light, keep pressing the valve/button down for at least 3 minutes with the multimer probes still on the thermocouple. Check the reading on the multimeter. When you try to relight the pilot light, the heat from the pilot will generate a current in the thermocouple, and the voltage will ... WebThe voltage should increase as the thermocouple gets hotter. A healthy thermocouple should have a voltage reading between 20 to 30 millivolts. If the thermocouple passes … the weir bistro bude
