SOURCE: my furnace is flashing 21

not sure what 21 is ,but if you are getting acode normally the code comments are on the door or the manufacture lable to tell you what they are...
i can tell you the operation and maybe that will help you out...
the unit should start off with the enducer draft motor small motor in furnace that pulls all the stale air out..then the negative pressure switch activates which should have a hose coming from the enducer draft moto to the pressure switch..once the pressure switch closes it sends power to the ignitor and the ignitor should glow once it gets hot a milivolt current is sent back to the gas valve and it opens up and fires...after it fires you should have a flame sensor small metal rod in the direct path of flame that keep sensing the flame and sends signal back to board.... unplug unit and watch it start where is it failing or in what part of the operation does it flash a code....

SOURCE: Model RRMA-AO42JK1OE Furance won't start. Red

Hi, is there 3 blinks followed by a 2 second pause? if so then you have a open limit switch on the furnace, a limit switch opens when the heat exchanger gets too hot. If you have a meter check the continuity through the limit switch if its closed you should read resistance if it's open the meter will read OL.

SOURCE: i need a list of

LED Flash list should be located on the inside of the unit's electrical panel by the wiring schematic, and by counting the flashes in between the longer pauses should give you the diagnostic code. A continuous steady flash can also mean normal operation, and something else on the inside could be holding you out like a float switch tripped (located on emergency pan underneath Air Handler Unit If Applicable) etc.

im reading your manual now for you at HP.com
my guess is lamp 5, (pwr) is not green now but is red
green means power ok, red means, not ok.,
page 2:
if flashing , the flashes are codes, what is your flash code if flashing
if not this LED then say which one?
green on 5 means ok. power ok, no errors. red bad.

Look at the inside of the cover on the furnace and it will tell you what's the code mean.
I think because was calling for Ac that's why you are having that blinking red light.
Turn furnace off on switch and turn it back on and that should clear error code .
To check your air conditioning unit that's the unit that's outside .
Check to see if contactor is pulled in .if it is and nothing is running then check the capicator. The capicator is the oval metal thing that's tuck next to the capicator with 3 wires attached to it .
If it bulky then it's bad .
That is the most common issue with these unit.

Just installed a goodman furnance and a/c, there is a blinking light on furance control panel, and the furance motor runs constantly even with the theromostat wire disconnected. thanks for any help


the thermostat wire that you connected to the circuit board is only too long and touching anouther terminal or the insulation on the green wire is bad or last but hardly ever, the fan circuit board is stuck ,which the factory test the systems before shipping out, so the problem is HUMAN ERROR on your part.Thanks, from koolbreezes!
