Answers :

Open the service panel to check for control voltage of 24volts when tstat calling, The contactor should be pulled in, if contactor is down,and contacts appear to be clean, and the unit is still not running, it is a bad compressor. to test this unplug the black wire from the compressoror at contactor,w/ power off! Turn on power if fan works normally it's a bad compressor. However if you see a swollen split cap(5 wires to a soup can looking w/ the terminal C,F,and Comp), switch it first and start at square one.
\015\012 You also need to consider the high pressure switch if its cycling on off on off.
The outdoor fan is controlled by pressure. If the pressure is too low, it will not come on. This can be as a result of too little refrigerant or low ambient temperature. Another reason is that the fanmotor capacitor is bad. Hope this sorts your problem. ratemeplease.

I have an Amana a/c unit and the compressor outside keeps stopping however the fan goes on. The a/c service guys have been to my house 3 times and the wires each time were burnt. The last time they change the capacitor and and new heavier guage wires and it lasted for about a month. When trying to turn iton now I am back to the same situation. Do you think I should I go for a compressor or change the unit ? It is a 4 ton model BBC60a2A and the outside unit model number is RCE42A2A . Thanks

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

Does the orifice, which needs to be installed in the inside unit of an a/c for a house, come with the outside condenser? I had an a/c system installed and an orifice was never installed. the original company says that they only installed the inside unit, and dropped off the outside unit, and we had a different company install that. The original company says that the orifice comes with the outside unit and then needs to be installed inside. Is this true? ( not sure if i picked the correct produ

I have reset the unit by switch it off for 5 minutes then back on and it worked for a week but now it makes the outside compressor go on and off the same number of cycles before it comes on.

I have an amana cr2-1 model outdoor air conditioner. We just bought the house and it did not come with a manual. I was wondering what we need to do to get it ready for the season. I have never had an air conditioner before, so I don't know anything about them. Do I need to do anything with the outside unit? Are there parts inside my house I need to do something with? Are there filters, or are they the same as the funace filters? I ask this because it looks like it is tied in with my furna

We installed a 4 ton downflow coleman air handler with evap coil Model number 1854s2m we did not change out the outside unit. the outside unit is a 13 year old 3 1/2 ton intertherm condenser the system is only generating a 10 degree delta T. My question is, this coil came with a factory TXV I am trying to find out is this a 10 seer or 13 seer coil is it compatable with the outside unit.

You have a missmatched system, for it to work try removing the orfice on the high side txv it is not allowing the evaperator coil to fill with refrigerant properly coleman and intertherm dont like each other since they control a large market in the ... Air Conditioners

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

Can a Goodman AC unit with a model number of a 24BTU-2 ton unit be upgraded to a 3 ton unit by changing the piston and the settings on the blower? They are also going to install a 3 ton compressor outside. Would this provide the same cooling capacity and performance of changing the actural HVAC unit to a 3 ton unit and would Goodman give me directions stating as much?

They would need to change the coil indoors to a 3 ton. If the blower speed can be increased it should be fine. ... Air Conditioners
