My lg lwhd7000hr air conditioner won't turn on there is power to the cord and the reset button stays on.

I just checked the manual for mine. Press the temp up/temp down buttons together to reset the light. It will come on again after 250 hrs of operation to remind you to clean your filter.

Hi friend, that's a great question!

To reset your Frigidaire air conditioner you would need to make sure the appliance is turned off and unplugged. On the power cord you will see a test button, push that button and you will hear a click. You would then press the reset button you will hear a click again signifying that the appliance has been reset. Then plug your air conditioner back in and it should be reset. -Matt

Good Morning Tina,

I understand that your Frigidaire air conditioner, model# FAM187S2A, beeps and flashes lights when you first plug it in. First, test the power supply cord by doing the following:

1. Plug in your air conditioner.
2. The power supply cord will have TWO buttons on the plug head. Press the TEST button. You will notice a click as the RESET button pops out.
3. Press the RESET button. Again you will notice a click as the button engages.
4. The power supply cord is now supplying electricity to the unit. (On some products this is also indicated by a light on the plug head)

NOTE:
• Do not use this device to turn the unit on or off.
• Always make sure the RESET button is pushed in for correct operation.
• The power supply cord must be replaced if it fails to reset when either the TEST button is pushed, or it cannot be reset. A new one can be obtained from the product manufacturer.
• If power supply cord is damaged, it CANNOT be repaired. It MUST be replaced by one obtained from the product manufacturer.

NOTE: Some plugs have buttons on the top.

I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if your air conditioner status has changed successfully. Hope this is helpful.

Obviously it is problematic machine from the factory so it will suggest a replacement.

Just replace the cord. I am unfamiliar with your unit so you may need to buy a new cord form the manufacturer but there is no reason to replace the whole unit.

hello
I would have the cord replaced.The test and reset is a ground fault,or a saftey device.
If its not working correctly then have it replaced

cause don't use an extension cord. probably fried the gfi or burnt other wires if you have a meter just test it

Just guessing, here. The reset is actually a "Ground Fault Interrupter" called a GFI. It's there to cut of power in case of a dangerous electrical condition--which you probably don't have.

Did you unplug the unit? If not do so, let the GFI cool for several minutes, and try to reset again. They're pretty hard to push in, maybe use a fingernail, you must hear a click or it's not reset.

Is there water in the outdoor unit, or is it filled with snow? This is the most likely cause of an actual GFI fault.

If the GFI itself has failed (unlikely), you could replace the entire power cord. You should then maintain safety by installing a GFI circuit breaker on that circuit, or you'll be in violation of codes that might affect your homeowners insurance.

There could actually be a problem with the unit. This would be that an electrical wire has come loose and is contacting the metal chassis, creating a shock hazard. Unlikely but possible.

If the receptacal you're plugging into is old and worn it might the problem. Worn receptacles might actually have tiny electrical arcs inside, which can trip a GFI. At a couple of bucks (DIY) it's worth a shot.

If there's actually an electrical fault in the unit it can be found and repaired, but the cost of repair could very well be more than it's worth. Warranty?

The reset button on the power cord has to be really pushed in until you feel a click. It is a soft button, so you might think you have pushed it in enough but you must feel the click. After the first reset you no longer have to press the button unless you have other electrical power issues that trip the button.

I am having the same problem. Have you had any luck, yet?
