If it is a digital thermostat check the batteries and replace. If you remove the thermostat cover so you can see the wires, check between R & W and you should read a voltage differential. Same for R to Y and R to G. Your problem may be only related to the batteries.

Need the tons for my unit. its really old and i cant read it on the side i have the model number it is 50ym042310 and it is a 230 volt unit. i know its a carrier because i amable to still see the brand...


The number you are referring to as your 'model number' is a number I don't recognize; maybe it's the SN or something - I don't know.
But that other number - "38CKC042" -------'is' --- your model number and the size of your AC is 42,000 Btu or 3.5 tons.

Hi All, I have a carrier reverse cycle airconditioning unit and about a week ago the digital thermostat blanked out. I spoke to an aircon repair tech and he suggested that the fuse is blown at the air...


It will be inside the unit main panel. Turn main power off and remove the main front panel. The fuse will be located on or near the fan control board. Typically they are a flat agc type fuse. 3-5 amps. The problem will be that if the fuse is blown -there is a reason for it. They don;t just wear out and blow. Look for frayed wires around the outside unit and in the thermostat to make sure you dont have a short. Otherwise, you will just blow the fuse you replace.

Blank thermostat


Check voltage at unit. Also check the 5 amp fuse in the unit. If this unit has a float switch in the drain line check that. Rus
