what can happen when a 120v igniter is installed where an 80v igniter should be?
I just bought a house and had the furnace serviced and inspected. The HVAC tech said that someone had replaced the igniter with the wrong one. That they put a 120v igniter in where an 80v igniter should be. He explained that is why sometimes the furnace would not kick on when the thermostat called for heat and that when it did kick on after trying several times it made a noise because of pressure build up. They did not have the parts available so now I am waiting and I am worrying about the furnace. What can happen when a 120v igniter is installed where an 80v igniter should be? Can the pressure build up get so bad that the furnace blows up? I am concerned and want to find out more.
Any information on what could happen would be greatly appreciated. Thank you!
