Question about Ruud UBHC Air Conditioner
Inside unit not blowing the air and the unit is freezing up. noticed on inside of unit that their are 3 lights 1# furnace 2# ok 3# power. the light in middle is flashing.
The flashing light may be a diagnostic light. So count the sequence of flashing lights and write the number down like this example. Short(flash),Short(flash), Long(flash) Long(flash), Long(flash.
Usually on the other side of the blower compartment door there is a list of possible failures that will coincide with the number of flashes.
My guess is that the system is low on refrigerant. This has caused ice to form on the evaporator coil that is above the furnace. The ice will block the air from moving through it.
You will need an EPA certified technician to recharge the system and locate the leak. Make sure to shut off the A/C and allow it to thaw before he/she arrives to services it.
There are other possibilities but this one is probably the most common. Good Luck!
