Furnace Help Not Blowing Hot Air

[crzy2bealive]

Well I got back from the river and my house was at 59 degrees….

Went to turn the furnace on and no air is moving between the supply and return.

Thermostat says heat on
Went into the attic and the diagnostic code is just flashing fast and per the panel it’s “normal call for heat”

Everything lit

Moved the fan to on instead of auto and nothing happened.

Video attached.

Anything I can check before I call someone tomorrow.

Control board?

 

[SoCalDave]

Not in heat or cool mode will fan run when TS is set to fan on?
If not I would agree with napanutt on possible control board issues.

 

[TPC]

Flame with no fan is dangerous. Don't mess with it, call the service people.

Control board?

I’ll take a multimeter to the control panel and see if I’m getting power to the blower wires

Just went through this, ended up being a bad board.

Our control board went out in CA during a cold spell. Probably around high 30’s. Took a couple days to get it fixed. Thought we were gonna die.

Fast forward to where we are now. High 30’s is a lot better than 14.

I pulled the heat-high wire and the cir-n.

Put the multimeter on the leads on the board and I’m not getting any voltage

I have the door safety switched taped and my wife turned the heater on at the thermostat.

 

[crzy2bealive]

Unless I’m supposed to check another wire.

Control boards aren’t that expensive if you’re trying to cut corners.

People in Europe had to turn to burning wood and coal to stay alive because of no electricity this past winter . Russia and Canada wouldn’t sell them any nat gas .

True. I guess the wife and I need to find some activities to stay warm.

Us gringos in the U S of A do tend to take things for advantage.

Part ordered on amazon let’s see what happens

That 2 wire deal .. pull that apart n clean the probe that should be attached to it..

I have don't that on our older unit last few years and starts working again.

Is there a low heat speed?

Look at the wiring diagram. Can you get a pic?

If it’s not working with the fan switch set to “on”, it might also be the motor or a capacitor if it has one.

 

[crzy2bealive]

Ok anyone know where I could source a motor locally or cheap online. Trying to stick with a good brand like trane.

Motor
5KCP39HGS599S

Capacitor
CAP11503O

 

[crzy2bealive]

I’m getting prices from 400 to 460 for just parts.

If that’s the norm oh well. Just wanting to see if the inmates know something I don’t

That’s less than I charged. Other peoples bids were $700 $750.

If the LED is flashing different trouble codes most always the boards gone wild & puked.

Factory boards in a new unit seem to
Puke in a few years,,, replacement boards seem to last and last - and Damfino why.

I don’t think you need a contractor’s license to buy from Grainger.

Ok blower replaced, capacitor replaced, board replaced.

Heater fires up, and the blower now turns on.

A/C does not come on…thermostat just flashing cool on

 

[crzy2bealive]

Nevermind got it working….I wasn’t waiting enough time in between heat and AC cycle.

Oops. Lol the heat got to my head

 

[SoCalDave]

Good deal!

 

[crzy2bealive]

Also, while I had everything out I gave it a good cleaning!!

I know. I could have taken the squirrel cage out, but I got lazy…..also I know I have weeds that need to be killed.

Cleaned the evaporator coils as well while I was at it.

And I bought this:

I think this coming fall season I will install a radiant barrier.
