CHECKOUT:
1. Check Operation
- Start the furnace with a call for heat.
- Inducer motor should start within 15 seconds.
- Inducer motor starts & runs normally → Step 2. Check Pressure Switch
- Inducer Starts + Makes Unusual Noise ⇒ Remove inducer motor and check for Item Stuck In Inducer
- Inducer but still very loud = Bad Inducer Motor
- Inducer Does Not Start + Code 3 ⇒ Check for 115V power to inducer.
- Power but No Inducer = Bad Inducer Motor
2. Check Pressure Switch
- Use a pressure gauge to check the pressure at the switch.
- Compare actual pressure to pressure rating on the switch (-.75" typical).
- Pressure Near or Below Rating = Blocked or Restricted Vent
- Pressure Well Above Rating + Switch Open = Bad Pressure Switch
