Problem with my Airtron Thermostat

I am having a problem with my 4 year-old AirTron/Bryant wallmounted unit. The display window on my downstairs unit no longerdisplays anything and the heater went off but the AC has turn on withoutshutting off. I've turned the AirTron switch to ''off'' yet the unit didnot turn off. The fan switch is on auto. After trying differentthings without any changes, I turned the circuit breaker off to keep theAC from blowing cold air continuously. I then purchased a new thermostatfrom Walmart and it still is doing the same things. Any ideas forrepair other than calling a technician just yet?

Two things, first go up to the heater and check the fuse inside the heater, looks like a car fuse. If that is not popped, then go outside to your AC unit and pull out the emergency disconnect. Check those fuses with a multimeter. IF you do not get anything replace those fuses, It has nothing at all to do with your thermostat.

Any unit over 20 years is no longer energy efficient & it is past the lifespan of an AC. Get quotes from 3 different companies & go with best price with best warranty. I'm not partial to any particular manufacturer. They all get their parts from overseas.
