Question about Air Conditioners

1 Answer

I have an older Carrier Gas Furnace. I can't read the complete Model number. But since Thursday morning, the blower just keeps blowing cold air, the spark igniter won't spark and the air damper will not open. I replaced the spark igniter and the pilot assembly for $215 and the thing still just won't light. As soon as you turn on the power the blower comes on and just runs. I check my 24v supplies from the transformer, and I am getting voltage. What else could it be. There are no LED's on the PCB.

Nothing will happen until the draft motor come on or the vent damper opens.  if that's happening, are you getting gas?

Carrier model fa4anf036 blows cold air periodically and doesn't keep the house warm. Eventually starts blowing warm air then cold again


this model number you gave is for an electric furnace , most often its found in mobile homes , if its undersized for the load of the home a larger unit is needed , if I look at this one right here , it says this one will provide 3.6 tons of heat this size will only heat a small area (about 15x25x7 feet ) and wall insulation will help increase this too , also the wall thermostat will " cycle" the heater on an off due to demand , if its placed in a drafty spot then that will affect proformance as well

I have a Carrier Gas Furnace Model # 395CAV024055ABJA, I works fine if you keep the temp low, like 68, so that it doesnt come on very often, but if you try turning it up and it needs to run for awhile, it...


It sounds like it is going into overheat mode. Check the overheat sensor, make sure the flue is clean, make sure any filters are clean, also check the gas passage inthe heat exchanger, if there is a blockage from soot the system will overheat

Furnace is blowing cold air.


You must have an electric furnace, gas furnaces only come on when the heater is warm. Electric heaters come on with the use of a sequencer. Your sequencer, tstat, and blower is fine, which means you must have broken heating element. I have a nice pictoral of how to restring one HERE

Furnace runs OK, but blower runs again a few seconds later


Could be a defective thermostat in the plenum.
When a gas furnace shuts down the fan(blower) will run until the plenum cools to the safe range. Usually 1 and 1/2 minutes.
Intermittent operation is a defective thermostat or relay.

(HVAC) Furnace Not Igniting Quickly


Make sure a back draft in the flue is not happening. Wind can blow it out until the flue heats up. The flame sensor may not be close enough to the burner flame. It may be weak and need to be replaced or if its an optical one it may be dirty and not see the flame very well. Its not wasting much gas but it puts extra wear and tear on the gas controls, is noisy, and, as you said, blows cold drafty air. A gas control system that has issues of any kind is not real safe. It needs to get fixed.

Furnace completes cycle but the (24volts)wont keep the gas valve on.


Depending on which model you have there is a fan limit switch or a fan control or pc board that will bring the fan on once the furnace warms up some so that it doesn't blow cool air. This could be malfunctioning or the blower it;s self is malfunctioning which could be a fan relay, compasitor, or the blower motor it's self.

Model number for Carrier furnace with issue for blower 5 minute off delay


I believe that this model number is for an air conditioner evaporator coil. This unit is probably directly attached to your furnace. The Model number for the furnace will be located in the compartment where the flames can be seen. It will be on a sticker or plate that contains lots of other information too like BTU/h, Volts etc...


The number you gave me gives me this info:
Cased air conditioning evaporator coil.
3 Tons
Horizontal application

Carrier Furnace wouldn't light, fan was running all the time.


Most furnaces have a photo cell if it gets dirty the photo cell does not see a flame so it trips the reset button on flame failure.
