Hi,I have a travel trailer 37ft. Problem with my ac, the fan starts good but my compressor does not kick on. My next door neighbour says it's the compressor that is done. Could you help me?


see this causes and fix it. God bless you
Motor Trouble Cause Diagnostic Procedure Repair Procedure Electrical Power is Off Check that all service switches for the equipment are in the "on" position.
Check for voltage at the pump motor or pump controls. If no voltage is found, check for voltage at the electric panel.
If power is on to the building, check fuse or circuit breaker serving the electric motor that won't run.
Check for local reset button on the motor (popped out = off )
Check for other power reset or power off buttons such as an access door compartment safety switch that turns off power to the equipment (found on A/C blower compartment doors)
Turn on "off" switches.
Replace bad fuse. Reset circuit breaker; if necessary replace bad circuit breaker.
Let hot electric motor cool down, then push in its reset button.
Be sure all safety interlock switches such as on compartment doors are depressed and that the doors are securely shut. Replace a bad safety switch.

Be sure proper breaker or fuse size in ampacity is installed - ELECTRIC PANEL INSPECTION Low voltage to the motor Check with VOM at the pressure control switch or at the motor wiring Be sure the proper size of wire is used for the ampacity and length of circuit; Test for low voltage to the building. Loose, improper, or broken motor wire Check wiring against the motor installation manual diagram, check all connections for tightness, shorts, burns, damage Rewire or repair or replace wWhen a sealed compressor motor has "burned out" this means that the internal wiring of the motor has become irreparably damaged: the compressor motor windings may be burned and shorted together or shorted to the steel shell of the motor, or the windings may have burned and simply become "open" or disconnected. If the motor has burned out in either of these ways it needs to be replaced.

I'm re-wiring a light fixture in our kitchen - went to shut-off the breaker and found that none of the breaker switches shut-off that circuit? When I shut-off the main breaker,it shut-off the circuit?...


When you shut off the main breaker it should shut off the circuit. However every circuit should have a breaker. Bad wiring. Call an electrician let him take a look

The circuit breaker for my condenser trips immediately after being flipped on. When the wires from the breaker are disconnected from the unit and the breaker is flipped on it does not trip. The...


Hello, usually the breaker will trip when there is a short to ground, this can be a high voltage wire loose and touching the metal or could be that the winding on the compressor has shorted to ground. If all the wires look secure and not touching metal that most likey your compressor is shorted to ground and must be replaced.

Everytime my central air unit kicks on my circuit breaker trips. It didn't do this last year or even earlier this year


A circuit breaker 'tripping' everytime the AC unit kicks on 'most always' indicates a direct short (somewhere in the condensing unit), although it is possible that the breaker itself is bad - (but not likely).

Usually the cause of this 'short' will be - either the condenser motor in the condensing unit (outside unit) or the compressor - also in the condensing unit.

If you're mechanically inclined - and "very careful" around electricity - there is a fairly simple way to find out which component is causing the short.

Step 1 - Make sure the condensing unit (outside unit) is completely disconnected (electrically) , i.e. pull the fuses/turn off circuit breaker on outside unit and turn off thermostat.

Step 2 - disconnect the condenser motor (this is the outside fan motor). Note: when you disconnect the wires of the condenser motor "be sure" you mark/write their location, and wrap them in electric tape.

Step 3 - start the AC unit. If the breaker trips again you can pretty much rest assured it's the compressor that is shorted.

To prove it (without a doubt) - go to next step.

Step 4 - "be sure circuit breaker and thermostat is turned off" - and - 'reconnect' the condenser motor - and - then disconnect the compressor wires (mark wires and tape them).

Step 5 - Start AC.

If breaker doesn't trip - you know it's the compressor that is shorted.

If breaker 'does' trip again - then it's possible the breaker itself is bad (not likely) or there is a 'short' in the condensing unit's "wiring" somewhere (not likely).

My guess is that either the condenser motor or compressor is shorted.

Hope this helps.

Good Luck!

I have 60 amp circuit breaker on my electrical a/c heater with a 45 amp fuse. I had the unit for 7 years with no problem. This month the 60 amp circuit breaker keeps tripping when the heater goes off. The...


You're unit is a 31/2 ton according to the numbers.Normally, breakers will only be in a half way posistion when tripped. Yes, under most conditions, the fuse will blow before the breaker trips. I have seen this many times, the breaker may be weak, burned, loose wires and so tighten wires, check the condition of the breaker.It sounds like the breaker even though it is 60 amps, is the problem and you should replace it with out hesitating. This will solve you're problem. When you pull the breaker out, look at the metal clips that snap in on the buss bar to see if they have been overheating.And the buss bar its self. You will know. I am sure this will take care of you're problem. Good Luck,

Fan blows but not cold


possible breaker is bad. Have an electrician do an amp test on the compressor which will tell you if the compressor is bad. That is the only way to test the compressor. I would change the breaker first due to the age of the breaker and (if it hasn't been changed out before) due to the amount of time the breaker has ran your a/c system. I f this breaker continues to trip I would have the units compressor checked on amps being pulled from electric service

LG S36AHP-UD7 Split Air Con. won't turn on.


Generally when an ac trips the main breaker and the breaker its self isn't bad, the compressor is going bad or is bad. To check you will need to do an ohms test on the compressor. If you get a reading of less than infinite, then the compressor is bad. You will need to test every lead going to the compressor which is usually 3 unless you have a crank house heater installed but they are not typical on a small unit. If the compressor has gone bad it is possible the it took the board out as well.

In my opinion turning on circuit breaker first is ok. First to determine what is tripping the breaker. Isolate what is on that circuit. There are always different ways of troubleshooting.
