american standard freedom 90 comfort-r maintenance, mine isn't working (PICS)


seems like this unit has never worked right even for 5 years

it seems to struggle to do something, not sure

listen to sound in video

http://youtu.be/b2fYT0TnCPI

keeps doing that cycle for 5 minutes

usually between 1 and 3 minutes it would eventually blow heat, but sometimes it would blow cold

now it only blows cold, never heat

is the ignitor coming on and if so is it staying hot until the gas valve opens? You'll hear a click from the gas valve when it does open.

I see you have some tools, you have a meter? Amps?

A minute (pronounced my-knewt) crack in the ignitor will still allow it to glow if the baord is telling it come on BUT that not visible to the naked eye crack will interfere with the ignitors ability to stay on. I have recently come across this problem.

What you do is check amp draw on the wire of the ignitor as it glows and see if the amperage drops out even a split second before the gas valve opens. I fit does then that is why your system is not lighting, tries and tries again and then locks itself out.

And ignitors don't get better once cracked, they get worse.

the reason the ignitors, ones with very small cracks which still allow them to turn on and get hot, drop out just before the gas gets to it is that as they get hotter once lit the crack expands, breaking continuity.

I'm betting this is your problem only because it was American Standard furnace that this problem occured on. I called an American Standard supply house technical support and they guided me through that diagnosis and fix!

7. RESET AFTER LOCKOUT
When the integrated control module has shut the
system down and gone into lockout, the system
must be manually reset before the unit will restart.
To reset, turn the system power off, then on, then
off and then on again within 30 seconds. This may
be done at the unitís power source or at the thermostat.
The system will not reset unless the procedure
off-on-off-on is completed within 30 seconds.

put everything back together and either post another video or describe in detail the sequence of events that happen with a call for heat. We know that there is a 2 flash but that could be due to a few things.

no, he did a lot of tests with voltages, and issuing the board direct commands, and it was not responding correctly, i watched him.

when the new board went in, all the tests passed, then he dealt with the condensation problem
