If you are experiencing issues with your furnace’s performance, it might be time to check and clean the flame sensor.
Here’s a step-by-step guide on how to clean a furnace flame sensor:
Step 1: Turn off the Power to the Furnace
Before learning how to clean the flame sensor on furnace units, it’s vital to turn off the power source. Locate the circuit breaker that controls the furnace and turn it off. Verify that the furnace is no longer running by checking the thermostat.
