Why does my outdoor 5 ton Goodman HVAC compressor not come on until I hose down the condensate coils when the Outdoor ambient Temp is 107 Inside Ambient is 85 and rising and set temp is 79?

The system is going out on either high limit or thermal cut off. 107 is a very high ambient temperature. Therefore your head pressure is through the roof. The condensing section of an A/C unit removes the heat from the refrigerant. You are trying to remove heat with 107 degree air, not going to work too well. What you are doing with the hose is cooling it down with the water, bringing the head pressure back down, the system will start again until it overheats. You should consider either a ground source heat pump or an addtional system for the household. Ground source heat pump uses water from the ground as the condensing section. No 107 degree air across a coil, but say 70 degree water. If that is not possible an additional system would help as it would bring the heat load in the house down, bringing down your pressures. There is nothing wrong with the equipment, it is just doing what it is supposed under such extreme conditions

Does the outdoor compressor run if you have an electric heat strip in your indoor unit?
Yes a compressor will run the entire heating and cooling cycle, unless its in emergency heat in which case you will not have compressor operation. Defrost cycle is the AC mode except the outdoor fan is de energized to assist in the defrosting of the outdoor coil.
3 year old central air unit will not run only inside blower fan goes on Circuit breaker is ok outdoor switch is on thermostat to cool and lowered indoor tempPossible causes?
Just to confirm: with central air conditioning, there are typically 2 circuit breakers: one for the inside blower unit (which is obviously working), and one breaker set for the outdoor unit. It's this second "double breaker" I'd look at first. Often, breakers trip and don't look like they're tripped. The only way to check for sure is to switch the breaker off, looking for a solid "click," and then turning it back on again. If nothing still runs outside, the possible culprits are as follows:1. If the "condensate" -- the moisture removed at the indoor evaporator coil -- is routed to a "condensate pump," it may be that that pump's sump is full. Is the condensate pump energized? Does it have a "safety switch" that shuts off the air conditioner if the sump fills up? If the pump's sump is full, and there's power to the pump, then the condensate pump may need to be replaced.2. Burnt/broken power or control wiring to the outdoor unit.3. Burnt/broken contactor in the outdoor unit.4. Deluxe outdoor unit senses a loss of refrigerant and shuts itself off (via the "low pressure safety" control).5. Failed outdoor fan motor has overheated the compressor, so neither runs.6. Failed compressor (due to internal failure or problems in the start components or burnt/broken wiring at the compressor terminals) keeping the compressor off. The condenser fan motor is kept off by a "condenser fan cycling control" which normally starts it after the compressor has built up refrigerant pressure.
Why would the compressor be on when the inside temperature is lower than the thermostat setting?
Your contactor in the outdoor unit is stuck closed.
Why does Ac trip breaker when on heat it doesn't?
That tells me the problem is with the outdoor unit. Most likely a dead compressor or fan motor. Additionally, your indoor and outdoor units are not on the same breaker.
Where is the ambient temp sensor located in 94 Labaron Landau?
The ambient temp sensor on a 94 Labaron Landau is located under the hood, near the front of the compartment. It detects the outdoor temperature and allows the vehicle to make adjustments accordingly.
What is a contactor for a Central Air Unit?
The relay actuated by the thermostat which starts and stops the compressor and condenser fan in the outdoor unit.
Constantly running air compressor for a Ruud electric heat pump What does this mean?
If the outdoor temp is around 35*or lower, it probably means nothing other than you are near the balance point when the unit should switch to auxiliary (electric) heat. At 35* or so & lower the heat pump alone can no longer extract heat from the ambient air effectively and you may also develop ice over problems on the outdoor unit. If these are not the temps you are experiencing when this occurs you should have it looked at.
Why does home ac compressor stop cooling?
This question is too generic. Too many causes, need more details.1. Does the outdoor fan run2. Is the compressor really running3. Is there a tripped breaker.4. Etc.
Why does the air conditioning compressor keep operating long after the system is turned off?
The contactor on the outdoor unit is probably stuck. Disconnect the power to the indoor unit, then disconnect the power to the outdoor unit and take a look at the contactor.
Do you need to shade your outdoor compression unit in this S.Texas hot weather?
Do you need to shade your out door compressor unit in this S.Texas hot weather?
Will 90 plus outdoor temps cause the service engine light to come on?
Ambient temperature Should have no effect on Service engine light Have vehicle scanned to determine the problem
Why isn't the air conditioner blowing cool air?
Is it a central unit? check and see if the fan and compressor are running in the outdoor unit. The system may be low on freon or the compressor may not be running. It is best to call a qualified HVAC technician.
