Hisense reset I have an Amana through-the-wall aircoditioner/heater. The outside air vent is set on closed, but it feels like I have a window wide open with the amount of very polluted and frigid air coming through the unit. Can anyone help?

SOURCE: unit blows cold air instead of warm (burrrr)

FAULTS ARE STORED WITHIN THE CIRCUIT BOARDS MEMORIE TRY UNPLUGGING IT FOR 2 MINUTES AND PLUGGING IT BACK IN

SOURCE: Coleman Evron CH/CA unit won't blow the air through the vents

Relay for fan operation in the cooling mode may be bad and not bringing on the blower for the air.

I have the same unit and was having the same problem. My brother works on A/C's and told me that the coils most likely needed cleaning from the inside out because when they are clogged with a lot of debris the system will overheat and cause that switch to trip and so far it has worked. What you need to do is turn the main breaker off to the outside unit first then take the four screws out of the top of the unit, use a flat head screwdriver and lift the fan it's self up out of the carefully taking caution of the wires going to the fan, then take the garden hose with a spray nozzle and wash the coils from the inside spraying through the coil to the outside and then wash the louvers off of all the debris and this should help.

If you have a heat pump probably there's a wrong connectionin the thermostat, but if is not a heat pump ,the compresor is not working or the unit leaked all the refrigerant.

Testimonial: "thank you, we have had a problem in the past with refrigerant leaking, was supposed to be fixed"
