Re: MY ELECTRIC FURNACE WILL COME ON BUT THE FAN WONT...
Check your amps on your sequencers. Ensure they are pulln the correct amps. Ensure you have continuity in your elements. They should energize with your blower. Your amps should not exceed 25 for each element. If this is too technical, then, ensure your filters are clean, restart the furnace by resetting the breaker two or three times. Pull off your therm and connect red and white wire together and see if it fires up.

Well Linda, is it the heat portion will not shut off or just the fan in the furnace that continues to run?? If the heat won't shut off, it will get uncomfortably HOT in your house, if its just the fan.....well, its just the fan.
More than likely its just the fan and it is running continually due to a stuck set of contacts in the control board or in the fan control board, if so equipped. If it is a furnace that is older than 15 to 20 years, it could be a mechanical relay that controls the fan directly off another control in the furnace vestibule that senses heat in the heat exchanger. If its an electric furnace, the first stage heat sequencer could be stuck closed causing continual fan operation and possibly one heat element is also energized. There are also several additional issues that could be the cause.
At any rate, its time to contact a reputable service entity to correct your problem. Good luck, Linda.
Home owner's manual? Troubleshooting section. Gas or electric?
If gas, pilot light may be out, or other gas controls. Are you sure you have gas supply? Do you have other Gas appliances so you can check? Furnace needs power for controls, fan and thermostat. Are you sure you have electric power to the furnace? Does the thermostat have a fan switch? If so turn it on and see if the fan turns on. If it does not turn on you may have a circut breaker poped. or some other reason power to the furnace is not working.
I wish I was a furnace expert but I will give a push in the right direction. When a gas/electric fan runs it has two speeds. When you turn on the FAN ON switch it should run at the slower speed. If it doesn't turn on or turn off again when you turn it back you have a wiring problem or a thermostat problem. Make sure the thermostat is compatible with your unit and wired properly (on both ends). The other time the fan runs is "in session" when heat or cooling is applied to the system. It should run until the system finishes the cycle then a bit more (30 seconds or 1 minute) to blow the treated air completely through the ducts. If it doesn't stop then you may have a bad fan time delay or relay. Check parts for your model and various appliance repair site online.
On a Trane furnace the fan realy must energize before the electric strips will come on. On the thermastat. See if there is setting for electric heat. This will bring the fan on and the strips should come on. First just turn on your heat and and turn fan to on postion if it works you need to set tstat to electric heat mode. Most of the time there is sswitch in the back of the stat that says gas elec. Turn to electric. Rus
OK so its an all electric furnace no gas? I cant think of anything clicking on an electric furnace except the sequencers or the safety switches.
If this is whats your hearing then the fan should definitely be running.
Feel carefully around the fan motor (I assume this is in a mobile home). See if you detect any heat coming around the blower area close to the fan motor. If so the fan motor may be at fault or one sequencer may be out (the main one of course...) the thing is can you get the fan to come on by turning the auto switch on the thermostat (or if older model the Auto On switch on the furnace) to ON? If so you can "limp by and have heat til someone either checks it or you can go on deeper into it. but to go deeper you'll have to let me know you know where the elements are and that you have a volt meter. and feel comfortable using it especially on HOT wires.
put the just the fan on turn off the ac and the heat and just fan on make sure the blower motor works cause thats really the only thing you utilize from the furnace in the summer and let me know
then if so does your heat work fine
