Not heat and replaced heat strip, now that works was open. Replaced main switch assembly and no great change.
SOURCE: Cool air when running; warm air when compressor is off.
It sounds as if warm outside air is being drawn back into the room when the unit is not actively cooling. Portable units depend on room air to carry the heat outside, & therefore will not work properly if the room is too airtight. Provide a makeup air passage by leaving the door slightly open, & see if this helps. Use a room thermometer to see if your desired temperature is being reached. Note that if the wind is strong & coming from the wrong direction, it may not be possible to prevent warm air drawback.

Hi,its possible have a problem your PCB Board ,the 17c is so cool setting but blows hot , and the E3 simble its min High Cooling , pls check ur PCB board to the nearest service center.
SOURCE: heats for 15 - 20 mins then blows cool air
Look for an outdoor thermostat/temp sensor and if you find one chack to see if its adjustable. (adjustments probably found on the board.)
It could also be wired to bypass the heatpump altogether when temps are below 40.
you will want to adjust, rewire or remove that t-stat/sensor.
In some areas they are really not needed. What state are you in?
