Question about Sharp Heating & Cooling
This is regarding my Sharp air con (Model: AH XP13NRV) inverter type with plasma ionizer 1.5 hp. After turning my air con about half an hour in cool mode and maximum blower speed, the blower will suddenly stopped and turns back up again. The indicator lights are still on and not blinking. No warning sound was heard. We did not turn on any sleep mode or any auto turn-off mechanism. Occasionally, the louver will flip itself to close position. This is very weird.

The Mitsubishi units have to be reset by turning off the indoor units by switching the remote or thermostat to off. Then turn off the breaker to the outside unit(s). After 30 seconds,turn on the breaker and then you can turn on the remote for cool. If no lights come on on the inside units, most likely you have blown a fuse soldered on the main PC board. At this point, call your technician. A goos tech will be able to wire in an in-line fuse holder so if it should happen again, you can easily replace the fuse. If you do see a light or two come on at the indoor unit but the outdoor unit does not start after 3 or 4 minutes, sounds like you will need to call a technician. Most likely you have a blown fuse on the main PC board of the outside unit. It is not an easy one to replace. Good Luck!

Could be the thermostat or the low voltage line to the outside. Usually a dog chews through it or the weedeater hits it and breaks connection. Turn on cool, go outside and see if it gets 24 volts to the two wires going to contactor (have to take off cover to get to it) DO NOT TOUCH THE CONTACTOR IT HAS 240 V AT ALL TIMES, unless disconnect is thrown, so turn it off. If you aren't getting anything, then it's either the low voltage wire broken somewhere or the thermostat malfunctioning. Make sure you turn off the inside unit before messing with thermostat or you will pop the transformer. If it pulls the contactor in, and you still aren't getting anything, then check for voltage on the load side of contactor (opposite from the inlet or lead side). If you are and you hear a hum from the compressor and the condensing fan motor is running, then it's your compressor. You'll have to remove the top cover to do the next step. Check to see if it when to ground by using a meter set on resistance and with the connector to the compressor removed, put one lead on one of the copper pipes going up to it and touch the other lead against any or all of the pinouts on the compressor. If you get a reading, it went to ground and you will need a new compressor or whole new condensing unit, depending on the age of the one you have now.

Isthis a window unit? It sounds like it. There could be a problem with your fan switch or the fan motor itself? Multi-speed motors can lose one speed at a time. It really sounds like the fan motor is bad. If the compressor starts in the cool mode, and the fan doesn't, the fan motor could be locked up. See, if you can spin the motor by hand? If you can, then something is bad within the motor. Now, if the motor has a capacitor, check for a loose or burned wire. Good luck.
