    Could be low or high pressure overload protection. Check for dirty filter, dirty condensor or evaporator, fans not working for the condesnor or evaporator. Other problems get more costly to fix.

SOURCE: no cooling after power out, indicator lights pattern not in manual

The Mitsubishi units have to be reset by turning off the indoor units by switching the remote or thermostat to off. Then turn off the breaker to the outside unit(s). After 30 seconds,turn on the breaker and then you can turn on the remote for cool. If no lights come on on the inside units, most likely you have blown a fuse soldered on the main PC board. At this point, call your technician. A goos tech will be able to wire in an in-line fuse holder so if it should happen again, you can easily replace the fuse. If you do see a light or two come on at the indoor unit but the outdoor unit does not start after 3 or 4 minutes, sounds like you will need to call a technician. Most likely you have a blown fuse on the main PC board of the outside unit. It is not an easy one to replace. Good Luck!

The upstairs ac display is blinking cool on, but not cooling the house. The outside fan is running. please help. The downstairs display and unit working properly


Normally Honeywell will "blink" COOL ON when its in a timed delay, usually 3-5 mins. And then COOL ON will stay on without blinking. If you turn tstat off then wait about 5 mins, then turn to cool, watch for the blinking, then wait 5 more. If it doesn't turn on, check/change the batteries if it has them. Try turning the AUTO/ON to the on position to bring on the fan only. It won't cool doing this but it helps in homeowner troubleshooting.

In my 2000 ford expedition my temp gauge keep jumping back and fourth when I run my ac. Y?


Running the AC does increase load on the engine, and thus heating, so if gauge changes gradually, this is because the compressor kicks in for a while, then kicks out. If cooling system is not working properly, small additional load could cause temp change. Other possibility is compressor going bad and causing excess drag.

If change is sudden, loose wire somewhere near compressor could be the issue.

My ac compressor broke. I had a new compressor and expansion valve replaced. It cools a little on high but not enough. Any ideas on the problem?


You need to check the refrigerant pressures (high & low) and learned the reason for the cooling problem-the gauges are the only way you could ever know what is going one with the AC-low pressures (both sides), low refrigerant-high pressure, over charged and not allowing the AC to cool.

Carrier thermostat


I hate to say it but Ive had trouble with Carrier's Tstats doing similar improper things. Unfortunatly the only repair is going to be replacement of the whole tstat. I recommend Honeywell's FocusPRO or VisionPRO tstat. Ive yet to have one fail and they have a 5yr warranty if they ever do.
