Question about Haier CPN12XH9 Portable Air Conditioner

1 Answer

The outside blower fan stopped working.... i diagnosed it was bad bc i had voltage right to the fan and nothing.... i am however able to use direct electricity from wall plug and the capacitor to get it to run but it runs very how...100deg C... and smells awefull... so i rewired it back into sequence with the relay on the main board and again i have voltage when the compressor kicks on ..... but no fan movement... also i have no voltage when checking power leg to neutral leg.... but power to ground i have needed 120vac... does this make sense to anyone... thanks .... oh and the capacitor is working bc without it the fan wont move at all.... even with direct ac from wall .... but way does it not work with the 120vac coming from board??? thanks Rob

I have came across motors that will spin freely with no power applied but when powered it seizes up. Sounds like bad motor windings. Not sure about how you are powering this motor, it is 240 correct?

SOURCE: Haier wall-unit AC wont work

Try unplugging the machine, waiting a couple minutes, then holding down the power button as you plug it back in. Hopefully you will hear a "beep". Then unplug it again, wait a couple minutes, and plug it back in. This procedure works for clearing the "E1" code from some of the Sharp models, so maybe you will get lucky and the same manufacturer made the control board in your machine! Couldn't hurt to try it out. ;)

This could be an obstruction in the blower cage or the blower could be bad.

SOURCE: My AC not working

Hi again,
The electrical supply needs checking in the outside unit.
Start at any supply fuses, and work around to the compressor.

If it is getting a supply out there, then it is a control issue. There should be a thermostat or controller that will turn the outside unit on if cooling is required. This is the defective part, as the signal to start is not getting there.

Check the outputs from the thermostat on the inside - one contact should close to turn the outside unit on.

Hope this helps. If it enables you to fix it please take a moment to rate this as fixya!

If not, I'll go on further

SOURCE: Gurrgeling noise after compressor kicks in

The sound that you are hearing is the refrigerant moving through the system. That can be a very normal sound. If you are not experiencing any other issues I think it is ok.

I can't believe that just sitting in a box can harm it. If it was stored in an upright condition, you should be fine. The system has oils in the compressor. So if it was stored upside down or something then the compressor could have run dry. This is usually ok if the unit returns to an upright position for a day or so before it is run.

SOURCE: Haier AC Problem Troubleshoot.

Your compressor is faulty, you could test this with an ohm meter or a mega tester to confirm that you have continuity between windings and earth or that the insulation on one of the start or run windings has overheated and broken down. Before you give up though, you can try to change the compressor capacitor, with same rated microfarad capacitor.

Fan blower not blowing

Most likely need a new blower motor resistor

My ruud sillouette a/c system inside blower does not run even on fan only. The outside unit works. The low voltage board is getting the 38vac power across the red and ground. The blower motor will work...

You have an meter check for power between R and G if there is no power, than the stat is calling for the fan and the fan relay on the board should be closed. Use your meter and with one lead to ground follow the motor lead, back until you find where it is stopped, that would be the problem.

Fan blower stopped working. I have changed the fuse and it has not solved the problem. The fan does not come on at any level.

Sounds like the blower motor, has gone bad, with test light, key and blower motor on, check voltage at blower motor, if you have voltage there, bad blower motor, blower motor sit under dash on passenger side, replace it.

The heater fan has stopped working on my 2000 Hyundai accent. Any ideas?

Perform a 'SHOCK' test of the blower motor (shock means HIT it. If it starts working, the brushes in the motor are worn out. If it doesn't start working, further diagnoses is required... check to see if you have power (battery voltage) and ground (continuity to chassis). if you have power and ground at the motor connector, then the problem is solved.. the motor is bad.

Blower stopped working.

Heater blower motor resister is bad, or blower motor its self is bad. Run 12 volts from an outside sourse to blower motor, if it runs its resister if not its blower motor.

Low Voltage At Heater Blower

When you tested the voltage they mean basically nothing without a load. No automobile fan will run at 1/2 a volt. Put the blower back into the circuit and retest the voltage. If you did indeed check with the blower in circuit, you do have a problem with the supply voltage. I would need to know what make, model and year to tell you more. As a temporary fix, you can rig a switch to the blower to supply 12 volts directly to it. It will run on high whenever you have it on, but it will work until you can trace back to where the problem is.
