Carrier-No Response to Thermostat Signal

CottagerRenoguy · 10-16-2011, 12:15 PM

I have a Carrier Model 58GFA130 furnace and this morning when I turned up the temperature at the thermostat the furnace didn't respond. I checked to make sure the pilot light was on and it was and the vent blower motor wheel was turning slowly. I disconnected the thermostat and crossed the signal wires and still didn't get a response. It didn't feel like there was any electrical current at the control wires as I thought there might be a small spark when they were crossed.

Not sure what to check next?

Thanks for the help.

which wires did you cross? R and W? next step is to check for 24V between R and C at the control board.

Hi,

Ii did cross the red and white wires. I can't seem to locate a control panel on this furnace where should I look and what does it look like?
It's about a 1995/6 vontage furnace.

Thanks

Your furnace may not have one. Normally they would be found in the blower compartment. If possible post some pictures.

It is on the blower...

Hi, I'm not able to post the pictures to this site. I did take another detailed look throughout the blower compartment and there is n't a control panel on this unit. I've done some limited work on furnaces and I do know what one of these generally looks like.

Any thoughts on what I should do next?

Thanks

Thanks, just saw the diagram and have located the panel. I'll check for 24volts.

Cheers

Well, scoffing to the picture Houston posted it should have one as he pulled the picture he posted from a manual for your furnace.
