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.

Go to Bryantrv.com and click on the Service Manuals link. It sounds like he missed a wire hooking it back up. There are usually 3 wires, red for hot, connected to the furnace and also a small blue wire with a red stripe, another small blue wire connected to varying colors but comes from the thermostat and a ground, usually yellow. There is a relay on the fan side of the furnace and a thermal safety on the back side, under the burner. The fan gets it's power from this relay and the furnace will not run until the fan is turning. It's common for the relay to go bad but I've only had to replace on thermal fuse in the last 12 years.
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.
If you do not have a fan board you have a fan limit switch. That brings the fan on about 120 and off at 90. It is located in the middle of your heat exchanger. Check across with voltmeter when you turn it on. If you have voltage after it runs for a while its bad. Or just jumper across it and see if afan comes on. They just go bad. Pick one up at HVAC supply house or you can order on line. If you have an electronic thermostat. On the back it has a switch that says gas or el switch to electric and the fan will come on with furnace. Rus but you still need to change fan limit this will just get you thru till you get it.
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
