Have u checked at the compressor unit. There is a contactor than energizes the compressor is this contactor getting supply when u turn on the evaporator this contactor get energized see if this happens. If this is energized and you are getting supply to the compressor and compressor doesn't turn on 1.) compressor has thermal protection this might be faulty 2.) or the compressor has too much freon 3.) check if the windings of the compressor motor are not short to ground

Remotes are a pain. Can you get into the unit to see the control box? You need to see if the unit has power. If its new enough it will have some diognostic lights so you can see if it has power. Without that its hard to diognose. Unit Model number is also helpfull. if it looks like the one on this picture it will be etched into a badge on one of the corner pillars. if its a plastic unit it will be on a sticker inside the unit

Tip

Freezer not working, things to check


The unit needs two fans running and good airflow, one fan outside cools the condensor coil and the other inside the unit blowing across the evaporator coil, warming it. The compressor must start up. The defrost timer stops everything and switches on a heating element to defrost the evaporator for several minutes. Please verify these conditions. The condensor coil may get clogged with dirt and lint, the evaporator may get clogged with ice build up, or the fan may quit working due to bad bearings, need for lubrication, or burn out. The defrost timer has an internal motor and contacts which may quit working, some have a way to manualy turn it to switch its mode in case it quits working.

Condensor unit freezes up.What would be the best way to cean unit without taking it out


unfortianatly without removing it your really not doing yourself any favors, it may stop freezing up for a short time but its only a half @#* fix. i am also assuming your speaking of the evaporator not the condensor, the condensor is outside the evap is inside

My maytag skybox does not cool very well even when turned all the way to high.


1) your box may be low on freon,
2) fault thermostat may cause unit run non stop,
causing evaporator to ice up and blocking air
circulation,
3) Dirt condensor thus reducing operation efficiency.

Check the simplest problem first - make sure condensor
coil is clean. if not, use a vacuum cleaner to clean condensor.

For # 2 is more likely if the evaporator has a fan.
If it has, check to see if it runs; it is behind the back panel inside box.
While at that, see if evaporator coil iced up. If it is defrost using hot water and turn it on setting thermostat to normal temp. setting.
If it work fine and later develops same problem, replace thermostat.

If the above 2 solutions don't solve the problem, call a technician to check freon.

that would be your evaporator core,go to your local library and look in a "Chilton's Auto Manual"this book has all the info and pictures for all types of auto repairs of all makes/models and will explain how, all evap cores come out differently

Uline combo unit. Condensor fan will not run and


You just answered your question. If no fan is running then the compressor will overheat and the compressor goes off on overload. Do you have the evaporator fan running? If yes then replace the condensor fan. Both fans will run at the same time. If the evap fan is not running then the unit must be in defrost. Since its a hotgas defrost the compressor will run.
Hope this helps

Have a near new panasonic cs-e28hkr split system air conditioner and the outside condensor fan continously runs even with inside unit is turned off? Thanks


Sir/madam,
If the inside unit (evaporator) is turned off absolutely.
The condensing unit must be turn off outside because the power
are derived comes from the evaporator.
Possible it seems on the cut out stage inside and remain the power still on
Otherwise theres somebody tamper the connection?

Fan cable consist of 3 wires
1 Common line
2 Start /stop line***Change the connection of this wire where it located, To On/ Off switch of the
evaporator inside unit
3 Ground green line/Earth

note: you can get all that wires inside the power supply in evaporator area.

If still under warranty inform the manufacturer

some older models ran power throughthe door/ light switches, for the evaporator fan, or perhaps even ewired through the defrost thermostat( reason for that is if evap is warm no need to run a fan and circulate hot air through the cabinet did you try letting run for a while mighttake 20-30 min to get cold enough to trip the defrost thermo.I usuallly hit it with a shot of the freon just ot freeze it shut real quick
