Having problems with your Air Conditioners ?

I also have a grunaire dual zone mini-split that doesn't work worth a ****. I've had it looked at multiple times and had freon r410a added twice and still nothing. Without the high side - how do you know if you put too much or not enough. I also have a long run on one system being over 25ft from the compressor so its a longer run - but that one at least worked for a moment - the short run - never worked. Get the FC fault consistently on one unit - other unit just doen't blow cool - how do yo


Answers :

An FC fault on a Grunaire is typically a defective PFC board in the outdoor unit or a Grossly overcharged system, where the drive cannot overcome the standing pressure to start the system up...

the ONLY CORRECT way to charge one of these units is to WEIGH in the charge..

the Label on the side of the unit will give you the correct charge amount.. this is for 25 feet of Lineset on Each indoor unit... typically on a 9 or 12k btu indoor unit (1/4" liquid line) you will add 0.7 oz refrigerant extra per extra foot of lineset.....

the PFC board failure is a very common failure on all of the grunaire / chigo built units...

I have a Bryant 561c central air unit. I replaced the capacitor, which was obviously bad. I also replaced the circuit control board with the relay insode, since one of the transistors was blackened. I can manually push the contct in and the unit will run, but no air will blow inside and the return compressor line will start to freeze over...any suggestions?

The compressor on my goodman unit runs a few hours and shuts off. The condensing fan continues to run and once in a while you will hear a buzz but compressor won't start. If you then turn up stat and wait, unit may start or sometimes you have to wait longer for compressor to run. Readings are fine and unit is clean.


There could be excessive heat developing causing internal overload protectors to open when it has reached that temperature. This could be due to bearing or winding problems with the compressor. Another possibility is the capacitor if it is not operat ... Air Conditioners

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 know this is late but I had to add a solution to this problem since I had the exact same problem and was able to solve it. The probelm is not your control board. On these units, the heat pump compressor will not kick in unless the temperature you ... Amana PTH123B25AJ Heat Pump Air Conditioner

Sanyo Condensing unit. blower fan doesnt come on unless unit runs,but unit only runs for about one minute and shuts off. led #6on cond. unit blinks and led on evap. coil #26 also blinks unit needs to be turned offon for it to restart.


First, the condensor fan is only supposed to run when the unit is on. As for the one minute run, then needing reset...this sounds like a "safety out". The air conditioner knows something is wrong and tries to protect itself. Being low on Freon wou ... Sanyo Air Conditioners

I have a York Diamond 90 Unit and my A/C quit blowing cold the other day. No Blower running, No Condensor or Compressor running. I replaced the capacitor for the blower motor and it started but no condensor. I checked the capacitor for the condensor visually and it was bulged out. I bought a new one (not the exact brand but I had a AC parts house match it up with the old one.) The new one has labels on the legs the old one did not. I have 3 wire leads off the condensor 2- Brn and 1-Red (New Capa


It sounds like you may have install it backwards. break the power and try again, if the compressor is trying to start thats a good sign. at least its not dead. Try re-installing the capicator and that might fix it, it wont hurt anything to try. ... Air Conditioners

AC Out. Two year old house. Goodman A/C, two units one for upstairs. Cleaned coils of both outside unit, replaced filters, re-set breakers. Upstairs is cooling. Downstairs unit is running outside, not circulating air inside (inside temp 87). Vents inside are cool to touch, no air. Outside unit fan is pulling, but air exhaust is cool. Compressor ? Should air be circulating even if compressor not functioning. Is there anything in attic exchange that would affect downstairs circulation. Thanks.


Assuming that the 2 systems are isolated, that there isn't any cross over between the systems...It is normal for an air conditioner system, from window unit to central, to be able to circulate the air, even if not cooling. This is known ... Air Conditioners

AC Starts normally but after some time of coolinf compressor in outdoor unit trips. Compressor running light in indoor unit remains on and outdoor unit fan remains on. But no cooling. After a break of about one hour AC works again and problem repeats.


Probably overheating. Check the outdoor coil and see if it is stopped up with dust, grass etc. If so, disconnect power to the unit, and clean the condenser coil with water or air. Be careful not to bend the fins if you use a water sprayer. ... LG Air Conditioners

I have two compressors-one for the upstairs and one for the down stairs. Both compressors are working but the air flow for the upstairs basically does not come out. You can hear the unit running but no air upstairs. Down stairs the air is working. Is there any way to turn the airflow up or adjust it to send more air upstairs. I had the capacitor replaced in the down stairs compressor a few weeks ago and for the upstairs about 1 1/2 years ago. when the air downstairs started working a few d

I have a 7 year old Goodman. The indoor unit blower keeps cycling on / off (it will run 5 to 10 mins them cycle off). The house is 81 degrees and the t-stat is set at 70; the condenser unit is compressor and fan are running. Both the t-stat and the capacitor was just replaced thinking that one of these items might be the problem.


Make sure the capacitor is the proper microfarad rating for the motor you have. Sounds like the motor may be drawing too many amps and dropping out on it's overload when hot, then when it cools it turns back on. ... Air Conditioners

My duo therm brisk air roof mount ac unit is blowing warm air, the amp draw on both the run and start lines is 3 amps, the compressor is hot, the condensor is not warm, the voltage across the run to common on the compressor is 120 vac and the voltage across the start-common is 300 vac.
