My Sanyo ac outdoor is overheating and then goes off what could be the problem

If the unit is overheating, I'm assuming the compressor is getting hot. It could be drawing high amps, do to a bad capacitor, bad motor, a dirty condenser coil. It also could be low on refrigerant and not getting the proper cooling back to cool the compressor.

I have a rooftop ac unit on my popup that was replaced two years ago. The unit works fine but I would like the fan to shut off when the compressor isn't running. Is there a switch for putting the fan...

Please describe your controls. Does it not have low fan, high fan, low cool, high cool on the dial at ceiling? If yes, low cool or high cool setting should shut it down when temperature is reached via thermostat dial.

When in cooling compresor will not re start unless you are at thermorstat,move control to heat and back to cooling

moving the stat from heat to cool etc resents a fault in the control board of the inside unit or outside. Usually a high or low pressure problem

Air not very cold. Any advice

Make sure the condenser fan and evaporator fan are running. Check your filters. Make sure the coils are not clogged with dirt or dust. Make sure the compressor is running. Get the refrigerant charge checked.

What does the mode button do?

The mode button can be changing it from low speed to high or if it is a heat-pump, from heat to cool. Normally, its the mode you want to run it in, if its only an a/c unit, it would have to be low cool, med cool, or high cool. Its unfortunate you have misplaced the manual as it can come in handy for trouble-shooting in the future. I would go back where you bought it and say it didn't come with one.

I have a Maytag portable air conditioner (about 5

when the compressor shuts off most of the freon goes to low side(cold) when it has a lot of freon to move and it works hard and you hear it loud after it has moved most of the freon over to the high side,the sound is less so not to worry it's normal if it clicks when it starts then you worry

High cool not working

Compressors on these units runs at only one speed. The change to high cool is only a change in blower speed moving air faster over the cooling coil. I would have the running capacitor for the fan motor checked. A bad capacitor can cause your type of problem. The other problem could be that the high speed winding in the fan motor is bad. Try it operation in the fan only position through the two speeds. If it works in the low and high speed for fan only your problem could be in the selector switch.
