My Goodman DSZ160361AE doesn't run. When I start it up it will run for about 4 seconds then shut off. I get an error code of 7 yellow blinks which means run circuit or compressor windings

Get rid of the hard start cap. Hard start capacitors should never be used in conjuction with normal compressor operation. Contact your local dealer for goodman and find the correct dual capactor for your machine and install it. Odds are your dual capacitor is either not functioning properly due to over voltage strike or it is the wrong size. On the wiring to your compressor, black is normally common and lead directly back to your main contactor. The red wire is the running lead and again normally goes to the c connection on the dual capacitor which leads back to the other side of the main contactor. The remaining wire on your compressor goes back to the herm connection on your dual capacitor. You may have swapped the wires for your power supply to your capacitor. I did this once and I figured it out about 5 hours later after I performed a wire by wire check against the wiring diagram. If you switch the wire around you turn the start windings into run windings and vice versa. They are not designed to be interchangeble. Just check your wiring against the diagram and the problem should clear up.
Hope this helps.

How to fix problem of Air conditioner doesn't turn on

If your central air conditioner doesn't go on automatically:
1) Be sure the thermostat is set to “cool” and that the set temperature is well below the ambient temperature.
2) A central air conditioner should be on a dedicated 240-volt circuit; check the main electrical panel and any secondary circuit panels for a tripped breaker or blown fuse. If you find the problem there, reset the breaker or replace the fuse.
3) Make sure the furnace power switch is turned on and that the outdoor condenser's power switch, which is mounted on the outdoor unit, hasn't been shut off. Also, be sure the 240-volt disconnect next to the compressor, which is in a metal box, usually mounted on the house wall, hasn't been shut off.
4) Turn off the power to the air conditioner and check the thermostat.
5) Remove the thermostat's cover and unscrew the wire from the Y terminal.
6) Turn the power back on.
7) Holding the wire by its insulation ONLY, touch the bare end to the R terminal and hold it there for about two minutes. If the compressor kicks on, the thermostat is faulty; replace it or call an air-conditioning technician. If the compressor doesn't go on when you hold the two wires together, turn the power back off and call a technician.

My fan wonT shut off

Good Morning Judy,

I understand that the fan will not shut off on your Frigidaire air conditioning and heat, air conditioner, model# LRA18HMT2, even when you have turned your appliance completely off. I suggest resetting your appliance, by either unplugging it or shutting the power off at your home's circuit break, for 3-5 minutes. When power is restored, turn your air conditioner to any cycle and let it run for 5 minutes before turning it off. I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if your air conditioner status has changed successfully. Hope this is helpful.

-Best Regards-

Mitsubishi ac keeps on turning itself off

If the compressor overheats, the clixon circuit will shut off the power to the motor to prevent damage. Then when it cools it will close the circuit and the compressor will again run to only shut down again.
The suction line going to the compressor should be cold - the cold gas returning to unit cools the hermetically sealed motor. If that line is hot you may be low on refrigerant.

Our power shut off. AC window unit was on. When power came back on, AC said "E1" Unit model no. HWR08XC7

The "E1" Code indicates a security protection shut down code. Based o what you said about the power outage and the restoration of power, I assume the unit was left ON during the power out and restoration of power. A power surge more than likely caused the error code.

Hopefully irreparable did occur and you can get the electronics to reset by doing the following:

Turn the ON/OFF Switch to OFF and unplug the unit for 15 minutes. After that time has elapsed plug the unit in and turn the ON/OFF Switch to ON. Hopefully, the electronics reset & reverted back to the original factory settings and the error code has disappeared and you can set the controls as you like. If that didn't happen, you should contact Haier Customer Support 1-877-337-3639, as they can tell you which circuit was effected. From there, you can determine if a repair is warranted.

Hope this helped you and thanks for choosing FixYa.

I have a ductless window LG airconditioner that keeps show P2; I have lost the owners manual so I can't remember what this means.

P2 indicates a circuit protection shut down. Turn the Unit Off & Unplug it for 15 minutes. Then plug the unit back in, and turn it ON. During that time out, the electronics should have reset and the unit will go back to your original settings. If this continues to happen contact LG Customer Support 1 (800) 243-0000.

Hope this helps you and thanks for choosing FixYa.

Since you had a power outage, you possibly have a circuit board issue. Try unplugging the heater for a couple of minutes then plugging it back in. If that doesn't help then a new circuit board may be needed. There are 2 different circuit boards. One main circuit board and one for the display. I hate to inform you of this but this are both very expensive. The main board will cost somewhere around $400. I'm not sure of the cost of the display board. If you have someone replace them, have them do to one and see if it fixes it. If it doesn't, put the old one back and replace the other, that way you can narrow it down to 1 or the other. There is a place in Ashville, NC that will repair monitor circuit boards. Go to this link and it will give you prices for the repairs. They guarantee their work for 3 years. If you contact them mention you heard about them from Niten's Heater Service. Sorry I can't be more helpful.

Hello kamper2 - Sorry for the delay in answering. I had a response prepaired but something cleared it on me about 2AM last night and I just couldn't think any more. Sounds like your problem is similar but different. I don't think you have to spend any more time on the roof looking at the roof unit. I have been working with a tech and Dometic for over 6 weeks. Right now I am running my A/C on an extension cord out my window and over the the power pedestal for power. The 12 VDC to the A/C circuit board is coming from a car battery sitting on my kitchen floor. The communication cable is a 25' telephone extension cord draped over my kitchen slide over to the CCC. Last week end I turned off all power to the trailer (110VAC and 12VDC) and sat here all day running just the A/C. It shut down 6 times. This was an effort by Dometic to eliminate RF energy affecting the microprocesser on the A/C control circuit board. Apparently the CCC and A/C control circuit board have some idiosyncrasies that aren't well explained. I also have an extended warranty on my A/C with Dometic. I'm thinking they believe RF energy may be picked up via the communication cable and affecting the microprocessor. Do you have a cell phone, wireless router for your computer or telephone or something that may put out noticeable RF energy? If you do, turn it off for a while to see if that may be related to the shut down's. I'm still working on my problem and no solution or reason yet. The circuit board in my A/C has already been replaced. I am assuming you do not have an icing problem with the problem A/C. If for some reason you decide to replace the communication cable from the CCC to the A/C circuit board, be aware that a typical telephone extension cord will not work. You must replace one of the plugs so the wires are straight through (pin for pin) and not reversed as the typical telephone extension cord is. Good luck with your detective work! azbill375
