When the air condition reaches the set temperature to cut off the blower motor keeps running and i have the thermostat set to auto on the settings.


check the operators manual but you will probably find that the fan will keep running so that the air in the room is circulated past the thermostat so that the temperature can be monitored and the compressor switched on when the temp reaches the upper limit

I have a Haier air/heating unit. The heat has stopped working.


Keep heating mode and temp setting at minimum 3 to 4 degree C* between room and required temp.

If still not working, replace the heating sensor.

Tnx

I believe this means you need to empty the water catch tray. Normally a pull out tray at the rear with a float arm in it. It will keep happening as the water is condensed out of the air during the dehumidification. Empty it out and start again, it will need regularly emptying.

Unable to reset monitor to put time in, it just keep showing 88:88 flashing


There should be a button or slide switch to put the Monitor heater in the clock set mode. Once you get it in the clock set mode, use the up and down buttons to set the hour (up) and minutes (down). Let me know what model the heater is and I can tell you definitely how to set the time. nitensheaterservice@earthlink.net

I cannot get my wintair room air conditioner to stay on! It keeps cutting on and off, going from fan to air conditioning. Need help!!


It sounds like your air conditioner is doing what it is supposed to do. The compressor kicking in and out is an energy saving method of using the ac. When the thermostat (ball attached to evaporator coil) registers the set temperature the compressor kicks off.

My air stops running inside before it get to the temp. Its set for but the outside unit keeps running and after a minute or two the air will start blowing inside again but the outside unit never turns off...


you have a possible thermal overload problem in your furnace blower motor dirt will cause this problem when it doesnt allow air across the windings of the blower motor if not dirt the motors going bad and getting hot use a shop vac and eliminate dirt keep your filter changed and your evaperator a coil may also need checked for cleanliness this will require cutting into plenum my advice someone qualified and remember dirt kills

This goldstar air conditioner model is WG2405RY7 It has an energy saver, but the unit just keeps running and won't shut off, everything else works.


Doe's the temp reach the set point? If not then it will run until it doe's. If you set the stat warmer and the fan keeps running after compressor shuts off check to make sure it is in power saver mode. Most AC units keep more even temp when fan is left on.
