Have a package unit that is tripping the circuit breaker early in the morning, around 5 a.m. each day for the past few days. The blower fan motor was recently replaced, but it seems to work fine, all day in fact, after resetting the breaker. (After letting rest for a bit before resetting the breaker.) Why would it only trip in the morning? It cuts off and on fine all other times, but only in the morning does it trip.

possible defrost timer or fan bad and tripping breaker

I'd check the manual to see if there is a circuit breaker for the motor that may have tripped. If it's all electronic, you may have a bad circuit board, blown fuse for said board, or maybe the motor bit the dust.

May be drwing to many amps even if it appears to look good by sight. Does the unit have a fan blower? Make sure the filter if any is clean and you have good air flow.

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!

Hello

Sounds like the motor or the heating element. Is it a heater? Get it repaired.

basic problems]
First check these:-
1) Over load cut off (try running it empty)
2) circute failur and fuse blown

sounds like fan motor is going bad - replace

You probably have a dirty condenser coil or the con den ser fan motor is bad or the blades are jam that's why it overheat and shut off by overload.

a full size refrige has to be on a 20 amp circuit, a 15 amp is just not big enough.. you should also know that this circuit has to be on a 12-2 gauge wire.. I also highly recommend installing a 20 amp HD receptacle

make sure that the circuit breaker for the electrical plug is not faulty, cause after a long lifetime of high amperage flowing through it, the springs will start to get weak. If this is the case then you need to replace the electrial breaker. Otherwise, make sure that the power system on the system is not pulling too much current, Or that there is not a faulty breaker inside the printer itself, which has become weak.
