I have a (Simple Comfort 2201) digital/non-programmable thermostat.

When I set the desired temp 1 degree below the ambient temp, the fan activates, but not the compressor, even an hour later still no compressor.

When I reduce the desired temp 2 or more degress, the compressor then activates.

It's as if the fan reads 1 degree but the compressor only reads a variance of 2 or more degress.

Does this sound like a new Thermostat is needed ?

THANKS
