Carrier air con. expansion valve 5 problems and 5 solutions

That may not be a problem. What's your outdoor air temp entering your condensing coil, the wet bulb temperature of the air entering your return, and the temp of the the copper line set?

You haven't mentioned the brand name. As the error code changes brand to brand I give some solutions. Check with your unit.
e-5 Outdoor activation of compressor over heat protection-Clean condenser coil and check out door f.motor speed. If less replace capacitor.
e-5. Blower motor lock Rotate manually. If hard to rotate, replace bearings or motor. If easy to rotate, replace capacitor.
Please mention brand name and other full details to get solution quickly. Thanks.

Before you buy, you have to calculate the heat load of your room and as well as the temp to be maintained in that room. Basing on that, there so many engineers in sales counter of every branded air conditioner to recomand you the correct model.And I hope with same expansion valve you can get required temp.

dirty evaporator filter and or coil, dirty out door condensing coil, defective thermostat.

Set the thermostat to COOl and lower the temperature control.

Could be an expansion valve or as well as the car might need a top-up of gas?

I Have encounterd this problem and the problem i  troubleshooted it down to was a defective switch
