• Flashing red lights on defrost board

    Jul.13.2010

    The outdoor air conditioning unit will not run though the indoor unit runs. The outdoor unit will only run if you manually push in the contactor. There are two flashing red lights on the defrost board on the outdoor unit. What is the problem and what can I do?

    Circuit boards have codes that indicate problems. Often the table to read the code is found in the wiring diagram on the door of the unit. If you cannot find or decipher the code, you should contact a quality air conditioning service company, like the ARS/Rescue Rooter branch in Laurel, MD at (301) 927-7100, to assist you with determining what the code indicates and to help you correct the problem. Homeowners are cautioned to seek professional assistance regarding problems with their air conditioning systems.
