You can find the contactor in the access/service panel area.

SOURCE: Compressor will not start.

If the unit is low on freon it will short cycle but a compressor internal overload will cause it to. Lets hope its the freon. Has it been frezzing up lately. Low freon is the cause most of the time. Make sure your filters are clean and both fans are running. Hi head can cause this to. (fans not running) How old is this unit. Maybe the coils need to be cleaned. Sound like this unit may need a check up and a good cleaning.

SOURCE: Ruud 5-ton 10 SEER heat pump compressor turns off after 20 minut

You may have cottonwood on your compressor. Before you spend any money, do two things. Rinse off your compressor to clear any cottonwood, and check your filters, they may need to be replaced. Hope that helps!

Hello,

Before ordering an expensive air conditioner service call to restore lost cooling capacity, here are a few simple steps to perform.

Check the Room Thermostat Temperature Setting: Set the thermostat to at least 5 degrees below room temperature. Our elderly mom has no patience with switches and controls. She regularly calls her air conditioning service company with a service request, sometimes late at night, because she has simply failed to set the temperature on the thermostat lower than the room temperature. Don't drive your A/C like our mother.

Check that the Room Thermostat is set to "Cool" not "Off" or "Heat". If the thermostat is not set to "cool" it is simply turning off your A/C.

Check that electricity is on
for the equipment. Check any service switches, including outside by the compressor, inside at the air handler, and fuses or circuit breakers in the electrical panel.

Check the Outside Air Conditioning Compressor: is the outdoor compressor-fan unit (the condenser unit) running? If not, be sure that the outdoor service switch and the indoor power switch, fuse, or circuit breaker are all in the "on" position.

Check the Indoor Air Handler: is the indoor blower unit running? If not be sure that the electrical power switch at your furnace or air conditioner air-handler is in the "on" position. Sometimes there is more than one switch, such as one right at the unit and another at the entry to the room where the equipment is located, or even upstairs on a higher floor if your air handler is in a basement or crawl space.

After doing all you should be able to fix the problem without calling a technician.

Thanks for contacting Fixya.

SOURCE: Compressor contactor not closing there

Sounds like an open in the stator coil itself if power is at it's source. Common in auto application as well where there is no magnetic field to draw in compressor drrrive plate/clutch. Ohm out stator for an open, Otherwise, physical debre/rust seizure can prohibit operation.

Brand New 2 weeks old 4 ton Trane compressor leaks a lot of water onto pad


If the unit is running in cold weather than there is ice building up on the coils located outside. This is normal in that the unit is running in heat pump mode heating inside and cooling outside, After the unit detects the ice build up it briefly reverses the cycle heating the outside coils melting(defrosting) the ice which you observe as water on the pad.

The video gives you an example of the defrost cycle!

2014 Dometic Brisk II 15,000 unit won't cool below 88 degrees


Check the unit to see if the outdoor fan and compressor are coming on. If not, check to see if power is reaching the contactor, both the high power contacts and the low voltage solenoid. Some contactors can be manually actuated, and a quick press (with a NON CONDUCTIVE ITEM) can show you if the contactor is engaging. If the solenoid is not working, check the wiring of your thermostat. When set to cool mode, there should be voltage on the solenoid of the primary contactor, sending power to the outdoor fan motor and compressor.

If the outdoor fan and compressor engage normally, then make certain the coils are free of debris and other blockages. If air flows freely and the compressor is running, feel the tubing for temperature changes. One side should grow cooler and the other warmer.

If the compressor runs but there is no temperature change, take your unit to a certified technician to check for leaks and system pressures. Roof top units typically use R22 refrigerant not R134a automotive refrigerant, which require EPA certification for purchase and dispensing.

Had 16 xi Trane heat pump installed 3 years ago. It ran well for the first couple of years. It began to stop heating and would blow cold air only. Have tried both aux heat and reg. heat to run and neither...


That's a complicated system that needs a qualified technician to service it. Lots of people can install them and they run fine, for a few years. Your indoor unit, operating on 2 heat elements, will feel like its blowing cold air even though its heating, just not so well. And not like you are accustomed to. Each element (5kw)=22.7amps, on average. So 3 elements operating should trip a breaker. Its probably been operating on 2 heat element plus the heat pump. And now you have trouble with the heat pump. If you can't TRUST the guys working on your equipment, try someone else. A second opinion. Normally a 3 or 4 ton unit will have 15kw heat installed, heatpump or not. 5 ton, 20kw. If yours is a 3-4ton, cooling, the 100amp(or normally two 60 amp) breaker should have been installed upon equipment change out. If yours is blowing cold all the time, something is wrong with your heatpump. The electric heat inside operates only when the heatpump can't keep up(real cold outside), the heatpump is in defrost(then it's actually in cooling mode), or if you have the tstat in aux/em. heat. Try a local trane dealer? Of a technician with 15-20 yrs under their belt. A trane dealer should have trane tech support also. BIG HELP!!!

Compressor doesn't run when called for cooling.


This could be a lot of things, there is a contactor relay in the system that might be bad, there is a possibility the contactor is not getting voltage, there could be corrosion issues with connections or a bad start capacitor.

We have a 3 1/2 ton unit the internal blower is blowing but the fan on the top of the unit is not turning and we have air blowing out of the vent but it is not cold model number gph1342h21ae


Hi,
If it is just the fan then the motor needs to be replaced...let it cool a few hours and then try it and see if it is just the fan or the fan and compressor that does not work...
If neither will start then either the t-stat is not working right or the contactor in the outdoor unit has gone bad...

I would check the outdoor unit, Trane uses "Sump Heaters" on their compressors
and when one fails it will blow fuses at the disconnect or trip breakers.
The sump heater is a small metal pencil sized item at the bottom of the compressor
with something that looks like lamp cord going to it. Also when the start capacitor
fails it will exhibit this symptom. Look at the can shaped items inside the cover
If they are leaking, or bulged this may also be the problem.
(with the breakers off to everything including the inside unit to prevent shorting
the transformer)
These are the most common problems and the parts are less than 20 dollars each.
I service 155 trane units at my properties.
hope this helps.

Hi,
One of the safety switches in the control circuit for the secind stage are bad... the contacts are pitted or corroded and are not passing the full voltage through...it will be hard to find the bad one because it will only do it under load...I would start jumping out safety switches for a short time and checking voltage to the coil til you find the culprit...

Check your CONTACTOR - the black "block" where all the line wires connect. Sometimes they stick. It's a cheap part, although make sure you take a pic of the contactor with all the wires attached BEFORE you take the wires out to get a replacement.
