Code 5 false flame blower comes on without command

Your furnace manual is at:

Sorry, your question is too cryptic to understand.


Take the cover off the burner compartment of the furnace. Observe the sequence of events that occurs at the furnace when you turn up the thermostat and post that sequence of events in order and in detail.

No diagnostic codes are listed in the manual. If you are getting diagnostic codes from the ignition control module, look for a list of what the codes mean posted somewhere on the furnace, usually on the inside of the fan compartment cover.
