On some of those inducer motors there is also a capacitor in the blower compartment on the left side of the burner section. It is possible that if you have 230v coming from the board CM terminals and if the motor is new maybe you have a bad capacitor in the blower section. Follow the wires to the capacitor and check microfarad reading to that capacitor. Caution there maybe 2 in this area but one is for the indoor blower motor and the other will be for the draft motor. The blower capacitor may be somewhere between 10 or 15 mfd but the draft inducer capacitor will be around 3 mfd. hope this helps
YOUR FURNACE IS IN LOCKOUT MODE DUE TO A SAFETY FEATURE OF UNIT. USUALLY THE HIGH LIMIT HAS BEEN TRIPPED, OR YOU PRESSURE SWITCH FROM DRAFT INDUCER MOTOR FAULTY OR PLUGGED. IT WILL CONTINUE LOCKOUT MODE UNTIL THIS IS FIXED.
If you can get to the shaft of the motor, oil it using electric motor oil. If the motor spins freely, you just may need to replace the start capacitor, however if it is binding; you will need to replace the inducer as an assembly.
31 PRESSURE SWITCH DID NOT CLOSE OR REOPENED - If open longer than five minutes,
inducer shuts off for 15 minutes before retry. Check for: - Excessive wind
- Proper vent sizing - Defective inducer motor
- Low inducer voltage (115VAC) - Defective pressure switch
- Inadequate combustion air supply - Disconnected or obstructed pressure tubing
- Low inlet gas pressure (if LGPS used) - Restricted vent
If it opens during blower on-delay period, blower will come on for the selected blower
33 LIMIT CIRCUIT FAULT - Indicates
The limit switch on the inducer has tripped. There are two wires that go to a small disk about the size of dime that has a small button in the center. Push this little button and you will feel a littl snap and the unit should fire up. Check all the manual reset limits as well. If the unit still won't start, jump the two wires by bypassing the limit switch. If it starts, then replace the switch. Bypassing the switch is only temporary and could lead to death if it is used as a permenant fix.
either the gas valve is not opening or your not getting gas to the furnace. also the gas valve won't open unless the draft motor comes on. if the ignitor is trying to light, but there's no gas, it might be a bad gas valve. i would call your closest NATE certified contractor
