Question about Heating & Cooling
Power surge during lightening storm this summer knocked out my thermostat. Installed new one but furnace won't come on.
There probably is a little transformer that runs the thermostat, at the furnace. If it is separate, it is easy to replace.

Check the data information on the unit there should be a troubleshooting guide that tells you what the two lights blinking once means. hope this helps.good luck. normally found with schematic

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.

Turn the power off to the Air handler unit.
Remove the thermostat from the wall, (Just the face part).
Look on the back side of the thermostat and verify that the jumpers are set to electric and not gas, otherwise the fan will not run during heat mode, they come from the factory usually set for gas.
If this is a electric heater this will solve your problem, If it is gas then it will be more detailed. Once you put it back on keep in mind that most thermostats have a 3-5 minute delay so just give it a little time and the fan should then work once you have the jumpers in the correct position.
