Here's how I fixed my Robertshaw thermostat that was stuck at a 70 degree reading for almost 2 monthes. When I turned on the air conditioner or heater it wouldn't stay on. I removed the cover panel and dusted off the inside which the guy at local hardware store suggested. That didn't work. Then I noticed the words "reset" right on the green circuit board on the left side. There's a very small silver button. I pressed on it and everything reset. Less than a minute later the thermostat is reading the correct room temperature. Now my air conditioner and heater are working properly.

You can get an operators manual on Robertshaw's web site. The fault could be that it's too co;d outside for the heat pump to be efficient. Once you get the manual you'll be able to find out exactly what's wrong.
