Do you know where the pressure switch is located on this furnace?
Thank you for responding back.
Ok. What you will do not is find the rubber hose and remove off of the pressure switch and the other end where it connects to the ports on the long black box. You will want to look inside these ports for any debris. You will want to also see if you can blow into once you put hose back in. Make sure you do not blow into the pressure switch. After you do this you can put hoses back on and give a call for heat and see if unit will run.
Ok. Have you ever seen your igniter glow yet?
Yes this is where your igniter is. Are you ready for some more hands on?
Ok. You will need to find the two wires that go to the pressure switch that you found earlier. Once you find these you will first need to shut the furnace off at the thermostat. Then you will remove these two wires. Next give a call for heat from the thermostat and be ready to jump these two wires together when your small inducer motor (just below your burner box) comes on. After these two wires are joined together you will look for the igniter to come on and the unit to fire off. After your furnace fires off shut down at the thermostat you will not need to let it run for more than a couple of seconds. We just want to see if it will fire off.
You can use a metal paper clip to join the two steak ons together. Both wires will need to make contact after the inducer motor starts up.
I'm sorry, I don't fully understand. I turned off the thermostat and removed the two wires. I'm not sure what you mean by jump the wires together. They have white plastic caps on them. Should I try to touch them together, or do you mean place them back on the switch when the motor comes on? should I remove the white caps from the wires? OK I just got your post about the paper clip. I'll try that
The inducer motor is not starting up. It only hums, unless that is what it is suppose to do. I did use a paper clips to join the two wires and nothing happened.
If your indcuer motor is not starting up this is going to be your problem. What is the serial number of this furnace?
Inducer motor has nothing to do with the AC. The purpose of the inducer motor is to pull the air through your heat exchanger and close the pressure switch. It should sound like a small fan and should be the first thing that comes on when you call for heat. The good news is this furnace has a 5 year on the parts and the inducer motor is one of those parts. Don't forget to put both of your wires back on the pressure switch.
Positive Feedback is appreciated!!
If the technician has done this before it should not take more than 30 minutes to do. He is removing five 1/4 inch screws and putting a new gasket behind the inducer motor. You can call a couple of different contractors and tell them what you need and let them know that the furnace is under warranty and ask each one what they would charge for the installation of an inducer motor. This could save you some $$$
You can put your zip code in this link for some contractors in your area.
