Blank screen sounds like a fried thermosat. Abrupt outages can affect certain types of thermostats. Make a jumper wire and jump across R and G. See if you get any action from anywhere. If a fan or compressor kicks in you know you have a burned out thermosat...

I would first check the condensate drain pipe. This can be done by blowing back into the drainpipe from outside. Not to worry it is not dirty or dangerous. Also make sure that your air filters are clean.

Please read through the following and see if you can pin point the problem. Write back if you need with more information and I'll walk you through what ever you find. Roger
Due to the many different questions I see about Air Conditioning, I am including this overview to help us better understand each other for trouble shooting. A basic air conditioning system has a Thermostat, Air Handler or Furnace Fan and a Condensing unit. In a split system, the condensing unit (Condenser) is separate from the furnace and usually in the back yard. When working properly, it blows hot air. It connects to the cooling part of the system by 2 copper lines. One large line and 1 small line. The part that cools the house is the "Evaporator" and is usually on top of the furnace inside the square metal box (Plenum). When the Air Conditioner is running, the large copper line should be cold and the smaller line should be warm. Common signs of low refrigerant are that both lines are the same temperature and/or frost or ice has built up on the large line at the condenser. The thermostat will normally display room temperature on till it is touched to change the setting. It could have a "Span" setting as well as times and temperatures. The operating "span" of MOST residential thermostats is 40 to 90 degrees. That means you can set it as low as 40 degrees and no higher than 90 degrees. It probably has a fan switch also. When in the "ON" position, the fan will run constantly, 24 / 7, but the condenser will still cycle on and off as needed to keep the house at set point. If you have a suggestion to include in this paragraph, please let me know.

I have an old Carrier N1340 air conditioner that works when switched on, green light flashes 4 times, for a few times then it shuts down. There is also a flashing red light inside that unit.


There will be a list of flash codes in your manual or on the inside cover of the unit indicating what the problem is eg. low pressure or high pressure alarm

The indoor fan or the outdoor fan? If it is the indoor fan the thermostat may be wired incorrectly or shorted. If the red wire and green wire in your thermostat maintain contact, the indoor fan will run all the time.

We had a similar problem. The timer light would blink 3 times, pause, then blink 3 times again, pause, and so on. The fan was blowing lots of air out, but the air was not cold. The operation light was off.

The technician came and fixed it for free, since it's actually easy to fix. He went to our circuit-breaker box, and cut power (from the box) to the air conditioners for 30 seconds. Then, he restored power - problem fixed!

It's apparently because the air con goes into a "safety" mode when there's a power surge.

The unit won't turn on an green light blinks


Reset the error by unplugging the power or turn off the circuit breaker for 10 seconds and power the unit again and operate. If it wont work then you need a qualified technician to correct the error.
