My White Rodgers 1F78 programmable thermostat shows a constant room temperature of 83-84 in the afternoon, but I set it at 77 throughout the whole day and night. Should I get a new one?
Room temperature on thermostat almost never agrees with temperature I programmed except for a while in the morning until noon

It sounds like the temp sensor is defective in the T-stat. I would replace it, get the newer programmable ones, they are very reliable and very cheap to buy online.
