Central Air Blower Fan won't start
Posted 09 June 2011 - 04:07 PM
If anyone knows how I could troubleshoot this I would greatly appreciate it. It is in the high 90's today and the wife isn't pleased.
The guy who installed the furnace has since moved south and the company that took over can't send a guy out for another couple days.
Thanks very much,

The good news is that you can do something until a tech (Hopefully a very experienced Tech) can fix the problem.
If you open up your furnace , somewhere you will see a circuit board with a terminal strip . There should be thermostat wires connected to the terminal strip. They will have printed on the circiut board the letters R , C , G , Y , W
Providing there is nothing wrong with the furnace control board or the fan motor here is what you do to get the fan motor going....
First turn off whatever switch you need to ensure that the furnace is not powered.
Find a piece of wire that will fit under those terminals. You need to place "Jumper" wire between the terminals labeled R G .
So now you have a wire going from R to G terminals. Turn power back on .
What this does is tell the heater to turn on the fan. If that does not work , you have a problem with the heater itself.

If it did not come on you are dealing with an issue with the furnace itself(a bad part or loose connection in the heater) .
** after you installed the jumper you did put whatever panels you took off back on, right?? many heaters have door switches that cut power to the heater unless the panels are on.

The tech called to reschedule he should be here in about an hour. I was hoping this would be covered by warranty but since they are not the company that actually did the work, as I mentioned they are an existing company that assumed his business when he moved, I'm anticipating them not wanting to give me a freebie and I don't know what should or shouldn't be covered. He could tell me it was the flux capacitor and I wouldn't know any better.

The furnace is a REgal Hi-boy with a Carlin E/Z-1 burner. I have attached pictures of the wiring. If someone could help me with this I would be very grateful.

The device with the 2 black wires(in the heater) and 5 screw teminals will be where you make your connections. if you look hard at the tan colored area you will see R G and maybe C or B .
What you need to do is identify what wire comes from the thermostst inside the house and extend that wire into the heater.
As I said in a previous post you can jump out the fan INSIDE the heater itself . Look real close at the device in your #3 photo. you will see the screw terminals have letters printed on it next to the screw terminals. place a jumper wire between R and G at heater , Not at the stuff on the ceiling.
