Question about Sharp Cv-p12lx 11500 Btu Portable Air Conditioner Ac

1 Answer

Air conditioner shudders, stops blowing cold, then resets every 5 mins

1) The air conditioner starts just fine, blowing cold. 2) Then, about a minute later, it shudders loudly and shakes, the cold air stops 3) There is a short period (15 sec) of loud, high fan blasting 4) Then it is no longer blowing cold, just fan, for 5 minutes or so 5) Then the cold kicks in again, and the cycle repeats. Needless to say, 1m cold out of 5 isn't doing much to cool the room. I have checked, and cleaned, all filters. I know this model of air conditioner has an internal reset to turn off the condenser, so it must be getting triggered. Can anyone guess what would cause it to shudder all of a sudden and trigger the condenser shutdown??? Thanks!

Simple test: the thermostat in your unit is electromechanical - unplug the unit from the mains, take it out and measure the resistance between the 2 electrical contacts, if it doesn't goes to near 0 when you turn it even a little bit then it's defective and it will have to be replaced.
If the resistance does indeed goes to near 0 then the defect is in the AC system. Another simple test: open the casing of the unit and put your hand directly on the compressor; now turn the thermostat button. If it doesn't vibrate then the starting capacitor of the compressor has failed and it will have to be replaced with a similar one.If it vibrates then the cooling circuit has got a leak and all the fluid has been lost. For that you will have to call a pro that will solder the leak shut and refill the circuit with the appropriate fluid - only he will have it, it's not sold on the customer market.

My unit keeps fluxuatng between cold air, then warmer air. It will start cooling then the unit seems to dim then amp back up sending out non cooled air.

Your compressor is drawing locked rotor amps. If the unit dims and then turns off a few seconds later, your compressor is going out on the internal thermal overloads. It could be a bad start capasiter or bad winding in the compressor. If you don't know electricity, it is not something I would recomend a DIY to fix.

My air conditioner is on but not blowing cold air and buzzes

The compressor is not starting. The buzzing noise you hear is the compressor trying to start and then the thermal overload trips. When it cools it will try to start again. Could be a bad capacitor or the compressor is bad. These two units need to be tested to see which one is bad. A capacitor is inexpensive. If it's the compressor it will be cheaper to buy a new AC.

Maytag M6Y18F7A Air Conditioner troble light turns off

you have to open the unit up or atleast see if the fan is failing. The blower motor is usually a double shaft and cool the compressor and also blows the air across the evaporator. Look for the air to stop blowing then the compressor to shake from overheating.

My Carrier 58dxc is making a loud noise

If your turning on heat and the unit is knocking and blowing cold air, your compressor is having problems in heat mode, could be reversing valve. A tech is needed in your situation. Getting the prob fixed right away will save you dollars..
