Answers :

First you have to hit the plus(more heat) and minus (more cool) and hit off twice then the unit should show c1 and wait till it shows L5 the hit the plus sign till you get to zero then hit off.
Unplug it, or turn the breaker off for 3 minutes, unit should restart.

I have a Goodman PC-060-1B All-in-one unit on a Double Wide home that I have one problem with and one question about; the problem is that the heating side is not working properly. I found the lower heating element to have a corroded connector, which could not be replaced, so I bought a new one and installed it along with five of the related control sensors around it. Now, if I turn the thermostat to heat, I can see the heating coils glow bright orange for about 1 minute and then the whole thi

Amana PTAC Unit is not producing heat. Fan works fine. can not locate manual reset for heat although a label on the unit says there is one. I have an Amana pth153b35ae ptac unit that the heat will not come on. The compressor will run in the cooling mode but not in heat mode. I verified the switching valve is working and the capacitor seems to be fine as the compressor will run in cooling mode. The thermostats seem to be functional because relays can be heard clearly when changing temperature se

I have a AMANA PTh153B50AE (PTAC unit). The air conditioner works fine. It is when I turn on my heater and it does not get warm. It just blows cold air. I have looked at the board and it appears that there are no bad spots on the board from where it had burnt. It appears that it may have a manual heater reset button. I am not sure if that will work but I can;t find the reset button. I am wondering if my heat pump has gone bad. Any help would be appreciated. Thank you.

I have the same problem, and I found the manual reset inside the unit. Turn the power off, and unplug the unit. Remove the outer cover of the unit ( inside cover ) , and remove the 2 screws holding the " wire mesh " in the front of the cover. Pul ... Amana PTH153B50AE Air Conditioner

My AC My Compressor keeps kicking off. I turn the unit on, the fan works. The Heat works but the compressor turns in about 60 sec. If I unplug the unit and turn it back on, it comes on but the compressor shuts off again after 60 sec. Can this be from dirt in the coils? They have some build up. Any other causes?

One might think so, YES the compressor is running till it gets hot and tripps on hi-temperature, and after it cools down awhile, the switch willcautomatically reset itself and back- & forth......Thank-you-very much! ... GE Zoneline AZ38H12DAD Split System Air Conditioner

I have a 10-year old Carrier Gas pack Model #48GS024060301. Turned on the heat for the first time this season and the unit did not turn on. I was able to turn on the house circulation fan and since it was a warm day today I also tested the A/C side and it worked fine. The inductor motor and fan were replaced last year. All the fins on the fan blade basically flew off on the first start up attempt last year. The entire unit, heating and A/C, were serviced within the last year by a certified p

I have an Amana Model GUC-C 90 Hi-efficiency furnace that we installed in 1992. It has a central air unit as well. On Friday we tried to turn the air on and nothing will work. I have replaced switches in the air unit in the past but this time there is no clicking, I can't turn the circulation fan on for the unit, the heater unit will not turn on. I have power at the breaker, and on the unit itself there is a on/off switch with a round screw in fuse, that fuse is good and I have power there.

I have an NewAir 12000H Portable Air conditioner with a heat pump. The problem is that the heat pump no longer seams to be working. The desired temperature is 79 degrees. the unit never gets above 75 degree. when it actually gets that high it because my heat from the house has turned on. once the heat goes off then the unit goes down to 72 degrees and stays there until my heat comes back on. whats wrong with the unit? is there anything that i can do?

Had a ac tech service central heating unit for the fall. Tech left and I left to do some errands . Now AC unit is not cooling its blowing warm air. I turned the circuit brks off and on inside and outside. I have also checked to see if unit was left on heater. thats not the problem. If I turn theAC on the fan does not turn on outside and there is no sound coming from the unit outside HELP!!! AC was working properly before this.

It may not help but it sounds like the tech took a control wire for the cooling circuit loose at the indoor air handler/furnace so that he could bring the heat on to check it, and forgot to hook it back up. That may not be the case, but if it is it w ... Air Conditioners

I have a Carrier Air HVAC unit, It is not heating the house. THe fan works, the AC works, but when I turn the thermostat to heat it will not come on. I am thinking maybe a thermocoupler. The model number is 585HJ036060. Where can I find a service manual for this unit?

My indoor unit on my heat pump will not shut off. The electric heat keeps running, and the fan keeps running. It only happens when it is really cold, like 25deg or below, above that and it functions fine. The outdoor unit shuts off, but the indoor stays running.

I figured the relay may be stuck, but if I turn the stat off, it turns off shortly after which tells me it may not be the c

Amana My Amana has a gas pack that uses a porcelain ignitor. The thermostat will turn on the unit, but it will not always ignite the motor will just run. I can turn the system off for a few minutes, then turn it back on and everything will ignite and run till the next time. Is there a sensor not working just right because the ignitor will ignite?

Yes, there is a flame sensor that will tell the gas valve to open, thus igniting the burners. When you say the fan is running is it the blower fan or the little exhaust fan connected to the vent. Because the blower fan shoul ... Air Conditioners
