To Next PageTo Next PageWhy my Intertherm Furnace is not working?
Your Intertherm Furnace might not be working due to several reasons. It could be a simple issue like a dirty or plugged filter, which you should check. Alternatively, the flame sensor might be coated, requiring cleaning with steel wool. A blockage in the condensate drain switch or a clogged secondary heat exchanger could also be the cause. Also, check if the evaporator coil is dirty.
What to do if my Intertherm Furnace fails to operate?
If your Intertherm Furnace isn't working, there are several things you can check: * Ensure the thermostat is operating properly. * Confirm the blower compartment door(s) are securely in place. * Verify the furnace disconnect is closed. * Check for tripped circuit breakers or a burned-out control board fuse. * Make sure the gas is turned on. * See if any manual reset switches are open. If these steps don't resolve the issue, further inspection by a qualified technician might be needed.
