Answers :

The small capacitor is for the fan motor the other for thecompresor .You can try conecting a booster (or hot start) in paralel to the comp.capacitor .If this doesnt work you have to replace the compresor.

I have 2 cental a/c units in my home. The 2 1/2 ton unit cooled great until abut a week ago. Now I cannot get it too cool lower than 78-79 degrees and it runs constantly unless I turn the themostat higher than 79 degrees. The freon level is correct, the coils are clean and so is the filter. What do you think the problem could be??

I like this one it challenging first do you know the refrigerant pressure?should be at least 65 psi for r-22 has any thing changed in the ducting? is the fan turning the correct direction?dan ... Air Conditioners

I have an old Miller 3 ton heat pump. It will work fine sometimes but when it decides not to work i can go outside and press the power contactor and the unit will come on as long as i hold the contactor pressed. A friend told me the defroster board could be the problem because when its cooler than 45 outside it wont come on by itself. But when i measured voltage at the thermostat no wire had 24volts.When it runs it runs good and cools or heats the house well.

It sounds to me you need just a really good tune up maybe a new contactor retest your low voltage what do you have from common to 24 volts it should be 27 volts if you test each wire you want get 24 v it will be like 7 or so ... Air Conditioners

If it is just the outside unit that will not quit running, it sounds like your contactor may be sticking. Remove the cover on the outside unit where the power goes in. You should be able to see the contactor. Turn the thermostat to off and see if it ... Goodman CKL60AR60 Air Conditioner

I am working on a M # GPG13420901AB. This is a 3.5 ton package unit that replaced a 3 ton package unit on 1700sq/ft single level home. Old unit was working fine but was replaced when the home was renovated. The new unit will not hold temperature in the home when outside ambient climbs above 83-85 degrees. Refrigerant pressures early in the day (70-80 degrees ambient) look fine 70 suction 200 high 9-11 degrees SH. Late in the day with outside ambients around 90-95 degrees, inside temps 75-78

It sounds like you are low on charge. I think you have a thermostatic expansion valve and you need to check the subcooling, you should have 12 to 15 degrees at 95. At 95 degrees your head should be about 280# for a 12 or 13 SEER unit or higher depend ... Goodman Air Conditioners

I have a new home that is near to completion. Two heat pumps (zoned) are installed and both are now running - house is completely closed and is comfortably warm. Only the downstairs pump is being used at the present. The upstairs thermostat is turned off. The downstairs pump cycles every 26 seconds, that is, on for 26 and off for 26. This never changes. The ext temp is about 56 and the thermostat is set to 68. The pumps are both contractor grade Carrier 13SEER, 2 ton units, and the total

Have a R-22 Rudd ait handler. Replaced the compressor with a 1.5 ton Goodman unit. My home is 1300 SF in NJ On hot days during the peak of the day the system seems to stop working for a period. The Compressor fan still runs but the compressor is not. My air handler fits the cubby hole and I am limited for space, as I considered replacing it.

I have a Tempstar 9000 airconditioning unit and while I was weed wacking I accidently cut a wire to the unit. I replaced the wire but now the unit wont turn on and also my furnace blower wont work even in the "on" position. I have a energy saver unit attched to the a/c unit as well. One wire connects to the a/c unit and the other to the energy saver. If I push the connector on the unit with the panel off the unit will run. Cansomeone tell me how to connect those four wires?

I have an old unit approx.11yrs old.When turn on for heat,kicks my breakers off. It runs for about 1/2 hr. before shutting off. Tried running the emergency heat bu t, it continues to kick the breakers off within 1/2 hr. Were can I find parts for this unit, I just need to get through the winter. I will be leaving this home come the spring. I do not want to spend the money on a new system for a home I will not continue to live in.

Well, obviously your furnace is overloading the breaker it is on. Try this, turn off the breaker that the furnace is on and go through your house to make sure everything else still works. Furnaces are large power users and should preferably be on t ... Amana Air Conditioners

1996 Coleman Model 7333C8876. Have 2 units on our Motor Home one day it was hot so I had both units running controlled by a Electronic Climate Control system. It got cool in the evening so I turned them off. The next day when i fired them both up on high the rear was fine. But the front will only cool on Low. The fan will not run on high and you can hear a slight noise coming from the unit. But the fan will not run on high.

I recently bought a 4 ton 14.5 SEER Rudd Spilt system using R-410 and matching Rudd furnace. This system replaced a Lennox 10 SEER 4 ton unit. Now that it has gotten hot in Baton Rouge LA 90-93 degrees. I have a programmable thermostat see bottom. It takes the one hour to drop the temp. 1 degree so starting at 5:00pm the unit runs non stop until 11:30 at night. The Lennox was about 3 times better and it was 15 years old.

Air Cools well but after about an hour, water starts coming into the coach through the discharge air side. Unit does not freeze up but if I shut the unit off, the tray that holds the water drains quickly, but doesn't drain well when the A/C is running. I always run it at high speed initially, though when you put the AC on Auto fan, it starts at high speed anyhow. This unit is in a Newmar Mountainaire 40' diesel pusher motor home

Your evaporator is probably dirty and is blocking some of the air flow so the air has to move around the coil and starts coming in through the condensate drain holes. That stops the condensation (water) from draining out the holes because the air is ... Dometic Rooftop RV Air Conditioner

Hi, We have two Paragon split systems which effectively cool our large home. One system is playing up. It started 3 days ago where there is water dripping from the front of the unit and the green 'run' light is now flashing. I tend to think it's blocked somewhere, buy my husband cannot find where to check this. Our outdoor units are both under the house with very effective ventilation but the last 3 days have been extremely humid, however the other system is running perfectly. Any ideas? Thanks,

More then likely the blockage is inside the a-coil section. At the drain. To get to it easier remove the pvc drain line. As the drain line comes out of the collection pan it goes into a pvc line the 90 degrees elbow goes to floor. So cut the lin ... Air Conditioners

Blower fan in the inside unit tries to turn on but wont. It can be turned manually and air conditioner comes on and runs fine. The " squirrel " cage spins completely freely and is not sticky or jammed. Is the motor bad or is it a run capacitor. Model number of inside unit is a49-15

Working on a Carrier sx from 1990, has three wire bi-metal pilot with spark and 100% lockout on the spark module. Homeowner says it only fails in cold o.d. temps (less than 35 degrees). Home owner finds unit off and silent, resets 120v and unit re-lights and runs. Don't know what parts have been replaced so far but it looks like a new spark mod. and the pilot was clean but I cleaned it again. Limit switch looks old but I think limit failure would cause the blower to run. Any ideas?

Hi, just replaced the capacitor thinking that would solve the problem but it appears it did not.
