Report "My white-rogers 1F81-261 model thermostat display went black for a second, then it shows it is on hold at 62 degrees while the temperature shows 72. (It's actually 64 degrees in that room. We have changed the batteries, done a reset per the manual, reprogrammed the entire week, and after about a minute, it returns to showing hold at 62, temp at 72. Is there hope?"
