Outside unit is running however it is not cooling.I cut off the circuit breaker wait 20 or so minutes and turn it back on and the unit works perfect for a while (no set amount of time ranges from hours to days) any ideas?It is a new unit and did the same thing when it was turned on for the first time.Worked 2 weeks before starting again.Unit is a little low on freon.It is a Goodman 3.5 ton ac only(gas furnace)

try switching to cool mode and try turning it on if this doesnt work unit may be blown.

You have to try resetting the system. First turn the breaker off for the condenser and wait about 20 seconds. After you turn it back on the system should reset. If you need any other Air Conditioning Repair help. Check us out online.

The bearings are bad in the motor and after the fan runs enough it eventually gets hot, making the bearing screech and the fan locks up. Need to replace motor again. See if it has a warranty. The reason it gets hot is because the fan is what removes the heat from the coil and if the fan isn't running there is nothing to cool it off so to speak.

call the technician
indicates a compressor problem
could be a failed start/run capacitor or compress failure

Hello, there is a short to ground somewhere, check all the wiring from the inside un it to the outside unit and make sure nothing is touching metal.

There are two things you can check outside before calling a service technician. The first is the breaker to the outside unit. There is a breaker or disconnect near the unit. If there is nothing wrong with the electrical supply, check the refrigerant level. If the level is low, the pressure switch will cut off power to the compressor to protect it from damage. DO NOT try to recharge the compressor yourself.

Your unit have dirty coil.
Shut unit off and clean the coil also change filter for indoor unit .Unit is shutting off on high head pressure

run cap may be bad
thumbs up

You need to verify if the problem is the unit or the breaker.  To do this, you will need to measure the current it is pulling from the power source.
If the unit is pulling too much current, then the unit is the problem.  If the unit is pulling as much or less than its rated current draw, then the circuit breaker is worn out.
The units WILL pull more power when hot outside.  It should not trip a breaker unless something is wrong with either the unit or the breaker.
A current draw test will tell you for sure.
If it's not the breaker, then it's probably low refigerant causing the issue.

The Mitsubishi units have to be reset by turning off the indoor units by switching the remote or thermostat to off. Then turn off the breaker to the outside unit(s). After 30 seconds,turn on the breaker and then you can turn on the remote for cool. If no lights come on on the inside units, most likely you have blown a fuse soldered on the main PC board. At this point, call your technician. A goos tech will be able to wire in an in-line fuse holder so if it should happen again, you can easily replace the fuse. If you do see a light or two come on at the indoor unit but the outdoor unit does not start after 3 or 4 minutes, sounds like you will need to call a technician. Most likely you have a blown fuse on the main PC board of the outside unit. It is not an easy one to replace. Good Luck!
