This is usually a bad contactor switch. Replacements on window units might be a little tricky, but if your mechanically inclined, you can disassemble the unit and find the contactor which pulls in when the unit is powered and try to clean the contacts, sometimes it works, other times it doesn't. Hope this helps!

How do I get the fault codes up on a Panasonic split air conditioning system CUE24FKR


14.2.2 To Make a Diagnosis1 Timer LED starts to blink and the unit automatically stops the operation.
2 Press the CHECK button on the remote control continuously for 5 seconds.
3 "- -" will be displayed on the remote control display.
Note: Display only for "- -" (No signal transmission, no receiving sound and no Power LED blinking)
4 Press the TIMER ? or ? button on the remote control. The code "H00" (no abnormality) will be displayed
and signal will be transmit to the main unit.
5 Each press of the button (? or ?) will increase error code
number and transmit error code signal to the main unit.
6 When the latest abnormality code on the main unit and
code transmitted from the remote control are matched,
Power LED will light up for 30 seconds and a "beep" sound
(continuously for 4 seconds) will be heard. If no codes are
matched, Power LED will light up for 0.5 seconds and no
sound will be heard.
7 The breakdown diagnosis mode will be canceled unless
pressing the CHECK button continuously for 5 seconds or
operating the unit for 30 seconds.
8 The LED will be off if the unit is turned off or the RESET
button on the main unit is pressed.

The memory data of error code is erased when the power supply is cut off, or press the Auto Switch until "beep" sound heard following by pressing the "CHECK" button at remote controller.
Although operation forced to stop when abnormality detected, emergency operation is possible for certain errors (refer to Error Codes Table) by using remote controller or Auto Switch at indoor unit. However, the remote controller signal receiving sound is changed from one "beep" to four "beep" sounds.

My 2003 VW Jetta air conditioning is cooling for a few minutes and sometimes longer and then it stops cooling. The fan continues to run but the compressor apparently stops running.


Have you watched the compressor in action? The compressor is driven by the fanbelt which turns a pulley on the compressor shaft, but there's an electric clutch that disengages the pulley from the friction plate attached to the compressor shaft. You should hear a click when the clutch engages and disengages. Do you hear that? Can you see the friction plate turning with the pulley or does it stay in one position while the pulley turns? If if works for a bit then stops turning, you may have a damaged friction plate such that it doesn't engage with the pulley. Take your car to an auto A/C specialist and let them examine it. It's also possible that the relay that sends 12 volts to the clutch is intermittent and needs to be replaced.

How do you turn off your freezer to clan it out and why does it run so long


Thank you for your post, friend!

To turn your freezer off you should be able to disable power from the control panel or you can disconnect power from your freezer to clean it out.

The compressor on your freezer will continue to run until the temperature has dropped to its setting. The thermostat inside of your freezer should tell the compressor to stop running. If you feel your freezer is running too long you may want to check to make sure the rear is cleaned out buildup of dirt or debris can cause your freezer to overwork. I hope this information is helpful to some degree. -Matt

Central ac compressor keeps running


Sounds like the contactor is stuck. Turn the power off on both units and remove panel on condenser. Pull out on the contactor if engaged. Likely still needs replaced, it's going to happen again.

You need to replace the fan capacitor. Your compressor is probably in thermal overload you can cure this by turning off the disconnect your ac voltage and taking a cool water hose and running over the top of the compressor for a while. Then turn your disconnect back on and listen and feel of the big copper line to see if it gets cold and also listen to see if the compressor kicks on.

I have a 1990 Cadillac Deville with the 4.5. I was curious if that car came with air suspension stock. I noticed a little compressor like thing right be hind the battery turn on when I was jacking it up....


The compressor will turn on when the rear air shocks are low. These shocks will begin to leak with age, and if new, can be damaged if you raise the rear end without disconnecting the battery. The shocks will fill with too much air and create a leak. If your motor runs continuously, you may need to replace the shocks. May also have a leak in the air hose going to the compressor. Check the fitting. Short fix would be to disconnect the power going to the compressor, but your ride will suffer.

Thirty amp fuse blows. Disconnected the compressor wires and the fan runs and does not blow the fuse. Is the electrical part of the compressor serviceable on it's own or does the entire compressor...


Hello, yes it sounds like your compressor windings are shorting to ground thus blowing the fuse. The whole compressor must be replaced in this situation.

RV A/C COMPRESSOR RUNS CONSTANTLY


You must isolate the problem by disconnecting the thermostat wires that go to the unit. If the compressor does not run when the t-stat wires are disconnected, that shows that the t-stat is malfunctioning, or there is a short in the wiring between the t-stat and the ac unit.

If the unit continues to run after disconnecting the t-stat wires, then you'll have to look in the unit for a stuck relay

DH30 Dehumidifier Compressor Does not Operate


I just picked one up at a tag sale, seller said it worked sometimes. Seems to have the same problem as yours. I took the time to tweak all of the connections and then re-soldered the control board with no luck. I finally disconnected the humidity control and it worked fine. By disconnecting the humidity control the unit defaults to it's highest setting and you have to unplug the unit to turn it off. Conclusion so far is that the humidity control rheostat is bad.
Note: Now while running the fan runs continuously and the compressor cycles on and off every 10 to 15 minutes. This may to be normal since the unit appears to be doing its job and I'm not sure how it is supposed to run since a purchased it broken.
