A061_F: Blower Fault - Motor Cannot Run
Status
This is a critical fault. The furnace will not operate in any mode.
Description
The blower has failed critically or there is a critical motor fault - such as thermal limit trip that prevents the blower motor from running.
Expected Operation
If the furnace was in heating operation when this fault occurred, blower operation will immediately stop and the furnace will shut down normally with post-purge at the correct speed. After the post purge (or immediately if no heat call was present), no other operation (including thermostat calls) will occur until this fault is cleared.This fault may be displayed in heating or cooling modes and may also be displayed in heating mode after the main limit control has been opened four times consecutively for more than 150 seconds (2m:30sec) each time. If this happens, the IFC determines that the motor and/or blower is not functional and enters a hard lockout condition requiring repair of the blower/motor and manual reset of power to the furnace.
Cause
1. The motor has tripped on thermal limit because of a restriction or bearing failure.
2. The motor Power Factor Correction (P.F.C.) choke is faulty and needs replacing.
3. The furnace model data is faulty or corrupted.
4. Wiring to the motor and/or P.F.C. has become compromised.
5. The blower wheel has become damaged or is not properly attached to the motor shaft.
6. The motor has failed catastrophically.
Solution
1. Remove obstruction or replace motor.
2. Replace the Power Factor Correction choke.
3. Replace the furnace memory card with the correct replacement part from ProStock.
4. Inspect and replace or repair wiring and/or connectors to the motor and/or P.F.C. as necessary.
5. Replace the blower wheel and/or attach the blower wheel to the motor shaft properly.
6. Replace the motor.
