SOURCE: Coleman 5KW gen motor shuts down when A/C switch turned on

Sounds like a problem with the wiring of the outlets after the circuit breaksr. Take apart the outlet box and have a look for burned or broken wires, melted outlets, and/or small critters stuck in the wiring.
I recently had to repair a generator that had its voltage regulator taken out by a frog!

SOURCE: Heater Burner ignites but main blower motor will not turn on.

it sound like the blower motor may be seizing up. try spining the blade by hand to see if it feels free or not. the motor could be trying to turn but can then tripping itself out on overload. (most motors have built in safety overloads which will trip during an overcurrant event. aka too many amps.) you may have to replace blower motor

SOURCE: home ac compressor fan won't turn all the time.

your looking at $175-$225 for just the single phase motor depending where you purchase, I just replaced mine(identical unit) due to screaming dry bearings, if you replace it your self make sure to keep new wires tight along side of unit or fan will cut them if loose and its a fan- 5mfd/25mfd compressor@440volt cap

SOURCE: I have a 33 gallon craftsman compressor model

i think you will find there is nothing wrong with the compressor part of this its all down to a faulty motor
if it cant start up the motor the motor will hum at first then the circuit braker pops out? yes???
check your getting full mains power first as if its trying to run on a very long extenshion lead its not getting the full power to start up, and you will need a much heaver lead,,,if its in a plug on the wall, change the capasitor on the motor,,,this is the part that hold a lot of volts to kick start the motor over when it first trys to start,,if this capasitor has droped in holding its charge there wont be enough volts in it to kick start the motor over,,so the motor starts to hum first trying to start but it dont stand a chance of spinning up
so it keeps pulling more and more amps till the braker pops out,,,watch this capasitor it can realy bite you if you tuch the two ends that are live????
the motor has two windings in it,,a start up winding and a running winding,, if its been humming for some time now it could have damaged the start up winding

My Compressor Atlas copco GA22 shut down and show warning Power Off. 12200000 11000000 9820 3978 09. How to fix this issue

The warning message you are seeing on your Atlas Copco GA22 compressor indicates a fault code related to the electronic control system. In order to diagnose and fix the issue, you may need to consult the user manual or contact a qualified service technician.
However, based on the symptoms you described, it is possible that the issue is related to the compressor's pressure switch or motor overload protection. If the pressure switch is faulty, it may not be detecting the correct pressure levels and shutting off the compressor prematurely. Similarly, if the motor overload protection is tripping, it could be causing the compressor to shut down unexpectedly.
To troubleshoot these issues, you may want to start by checking the pressure switch and ensuring that it is functioning properly. You can do this by checking the electrical connections and testing the switch with a multimeter. If the pressure switch is faulty, it will need to be replaced.
If the pressure switch appears to be working correctly, you may need to check the motor overload protection. This can be done by inspecting the motor and checking for any signs of overheating or damage. You can also test the motor with a multimeter to ensure that it is drawing the correct amount of current.
Ultimately, if you are unable to diagnose and fix the issue on your own, it is recommended that you contact a qualified service technician for assistance. They will have the expertise and equipment necessary to diagnose and repair the compressor.

At night its shuts down when the therm is satisfied,but trys to restart right away and when it does start it shuts down right away and just keeps doing this

The thermostat has a differential built into the temperature sensing operation. The differential is normally a degree or more. If the stat shuts down at 72 degrees it should not start the unit again until the temperature in the room reaches 73. If the AC runs and cools properly until it shuts down, I would check the thermostat. The AC can not restart immediately after it shuts off because the pressures in the system are too high at the compressor. It takes a few minutes for the pressures equalize allowing the compressor to start. If the stat tells the unit to start under high pressure, the compressor will shut down on overload. It will start and run after the pressure falls enough for the compressor motor to run.

Leapfrog ipad ultra black screen white dot

During a normal shut down, the screen image on a LeapPad will reduce to a white dot, which will disappear in five to ten seconds.
In rare circumstances, the white dot will not disappear and the LeapPad will not fully power down. If the LeapPad does not complete the shutdown process and the white dot remains on the screen for more than ten seconds, complete the shut down by pressing and holding the power button on the LeapPad for ten seconds. This will fully power the LeapPad down, and it will start up normally next time you power it on. For more information contact essay writing service reviews

We have a tempstar down draft furnace. 2 years ago the heat exchangers where replace because we were told they were cracked. This year the downdraft motor was makikg a lot of noise & we were told the...

Sounds like the low limit or high limit is out these control the fan motor.They are usually set to kick on around 150 degrees and set to go off around 95 to 100 degrees. Over heating does happen with cracked heat exchangers and it can possibly take these two items out. Normally your furnace should run approximately five minutes or a little less then your fan motor comes on and then for cooling down burners should drop and the fan motor should run again roughly five minutes or so then shut down. Times may vary as to your settings.

Stuck in defrost mode after changing timer and thermostat

Amana adaptive defrost:

Press refrigerator light switch five times in six seconds to initiate defrost cycle. Pressing five more times within six seconds will cancel defrost and go straight into the run mode. Similar operation on both bottom mount and SxS refrigerators. After the defrost terminator/thermostat opens, six minutes of dwell time occurs before the compressor and condenser fan motor will operate. After defrost terminator/thermostat open, 10 minutes of dwell time occurs before the evaporator fan motor will operate.

The motor in our AC has gone out 2 times in less than 5 years

I would ask what kind of service was done on your system over the period of time from the time you first had it installed? Were there service calls for leaks in your system and were the leaks located and repaired ? When the first replacement compressor was installed was a filter dryer installed? Is your area subject to voltage variations? New condensing units normally are covered for five years on the compressor.
