Limit open more than 5 minutes (blower failure suspected)
On GMEC96 / GCEC96 / AMEC96 / ACEC96.
The limit circuit has been open for more than five minutes, so the control assumes the indoor blower has failed. The inducer keeps running and the furnace does not heat.
This needs a licensed gas technician. There is nothing safe to check yourself. Leave the covers on and book a professional.
This involves the gas supply or burner. Only a licensed technician should open the unit or work on gas parts.
What causes it
-
The indoor blower is not running. A technician resets the main power and checks the blower.
-
A manual-reset rollout switch or limit has opened. A technician finds out why and resets it.
