SOURCE: What's the deal? Wont shut off or respond to thermostat. . .

Red= power........White=heat.............Green=fan.................(grey)-(yellow)=cool .....these are the connectons. Disconnect these wires from the thermostat and know that red/power is the only wire that send power to the thermostat, and the rest sends it back to the unit to call for whatever,, red--to . white for heat... red to green for fan .... &red to grey for cool! OK! Turn all your power on, and use a jumper wire from red / green for fan and see if the fan comes on! Then move the jumper wire from red to green , to red / to white for heat and the fan , wait for 3 minutes before removing and going to the next step. Then red /to grey for cool and check if the outside comes on. Either you have a wire touching past the insulations and making a connection, a bad thermostat ,oe excessive wire lead touching the next connection.Thank you very much!

SOURCE: (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.

SOURCE: Carrier 58 Series Furnace Blower Motor Won't Shut Off

Yes. If the high limit is tripped, the furnace will bring on the fan continuously until the limit resets. Often, they will not reset if tripped repeatedly. If the furnace is too large for your application, you probably are not able to move enough air to keep the heat exchanger cool enough.

I am getting one light flash indicator limited circuit issues. The furnace fires and heats up but blower does not come on

Remove the blower motor, With the furnace circure breaker off!!!!!!!!!!
Put a universal 115 v plug on the two wires and hold it on the floor and plug ER in. It's a 115 motor, look at specs to make sure. If she don't , check wholesale house to get a motor. If not that, motor capacitor, then contact switch if capacitor don't do it. Be very safe!!!!!!! . The capacitor will need to be discharged and if checking it, do NOT
Touch both post. Discharge it before disconnecting it by turning all power to furnace off, taking a screw driver and putting it across both terminals. It will arc. Do that a couple three times to get rid of stored electricity. If it does arc with a little snap and spark, it's good.
BE SAFE. Hope that helps.

The combustion blower is easy to replace. You may be able to prolong the life of the motor by applying lubrication to the shaft bearings. If the motor is too far gone then replacing it is the only option. Just remove the screws that mount the blower case to the heater, disconnect the wires and reverse the steps to install a new motor.

How do i replace the start capacitor on my furnace in the attic?

There actually is no start capacitor in the furnace, but there is usually a run capacitor. The run capacitor is mounted on the blower housing. Turn the power off to the furnace and remove the blower door. Look back at the actual blower motor and follow at least one brown wire to a metalic oval. That metalic oval is the capacitor. Remove the wires and make a note of how it is wired and install a new capacitor of the same microfarad value. The microfarad value is marked something like 5mfd or 5uF (it may be 3, 5, 7.5, 10, or 15 microfarads. Make sure to use the right one or you can cause failure to the motor.

I dont know how to remove the blower motor

Hi, I need to know what type heater you have. If you have a furnace, gas fired in the garage or a closet, kill the power.Remove the panel to expose the blower motor. Mark your wires as you will have 3 to 4 for different speeds.There is a hex screw at the front corner of each side to remove.Grab the blower housing and slide it out of the furnace. To take the motor out of the blower wheel, loosen set screw on shaft. Use rust buster on 1/2 shaft. Loosen belly bracket on motor, and tap the shaft end until the motor falls out. If you have something different, please let me know what you have and I can help you.
