Replace blower motor it's burned up.
Bad low limit switch,fan switch.
increase the efficiency of the system
If you are refering to the inducer motor( the one with the little wheel that you see when you take your units doors off) Yes it should keep running when your blower motor is running and before ignition to create your draft and during to rid the gases out your flue Hope I kept it simple
Sometimes the blower is always on, at a low speed. If you have a system that turns off the blower completely, then you should hear nothing.
turn off power to furnace and remove the bottom door to the blower compartment,the filter should be on the right side of the blower housing or it may be directly below the blower housing on the bottom of the furnace depending on how your return duct is run. hope this helps,FYI filters s/b replaced or cleaned every 30 days.
There is a delay on the fan to allow the furnace to get hot so as not to blow cold air into the home at start up. There is also an `OFF` delay, where the fan runs for a minute or so after the flame shuts off. This is to cool down the furnace.
what is the sequence to a gas furnace ? The sequence how a gas furnace works normally is : thermostat calls for heat, blower comes on for a few seconds and is shut off, gas valve opens and an igniter lites up and burners come on giving heat to the heat exchanger. When a certain temperature is reached depending on the make of the furnace normally around 120f blower comes on. When temp. is satisfied the gas valve closes and burners go off. Blower stays on until the high limit cools off to around 80f. Next cycle will go again when the thermostat calls for heat. For any work on a gas furnace a qualified technician is recommended.
Heater motor switch and or the connection at the switch is melted. Also check connections at the blower motor and blower motor resistor for melt down damage.
sounds like problem with tstat programming.
Your blower motor working even after the car is off is a good sign. This means that the car's system is preventing your car from overheating.
Probably a bad blower motor. Try tapping the blower motor gently with a hammer when it isn't working. It that makes it work, replace the blower motor.
