How To Test A Gas Valve On A Furnace In 5 Steps

How To Test A Gas Valve On A Furnace In 5 Steps 5. test the valve. use a multimeter to check the voltage at the gas valve during a heating cycle. if the readings are inconsistent or there is no voltage, there may be a problem with the wiring or control board. sometimes, these issues are symptoms of the furnace gas valve not opening properly. 6. adjustment (if applicable). If you're trying to figure out how to diagnose a bad furnace gas valve, this is a video that explains what the gas valve does, why it's important, how to fig.

How To Test A Gas Valve On A Furnace In 5 Steps How to test a furnace gas valve. testing a furnace gas valve is a crucial aspect of ensuring its proper functionality. following these steps can help determine the gas valve’s condition: shutdown process: to initiate the testing process, it’s essential to prioritize safety. start by turning off both the furnace and the gas supply. Step 5. hold each tester wand on the multimeter to one of the terminals on the gas valve. a normal reading will be in the range of 145 to 195 millivolts. readings outside this range indicate the gas valve is defective and must be replaced. furnace gas valves cannot be repaired. furnace gas valves are wired to an electronic component known as a. Check the inlet and the outlet side to see if the pressure is dropping on either side of the valve. another reason the flame could drop out after only a few seconds of burning is the flame sensor. if the sensor doesn’t detect the flame, the control board will signal the gas valve to shut down. Disassemble and inspect the gas valve. to gain access to the gas valve, start by removing the front panel of your furnace. once exposed, locate the pilot light assembly and disconnect it from the gas valve. next, use a wrench or pliers to loosen and remove any nuts or bolts securing the gas valve in place.

First, turn off the power to the furnace. then, remove the access panel to the furnace. locate the furnace gas valve and make sure it is in the “off” position. next, turn on the power to the furnace and use a multimeter to test the voltage at the furnace gas valve. the multimeter should read 24 volts.
