We have Aprilaire Model 8348. We keep it set at 75° in the summer. At times, it will read 75° and stay on for a couple of hours or more and we have to shut it off manually. We then leave it off for 30 minutes or so and it stays off until it reaches 76° again and then comes back on. Could the thermostat be malfunctioning?
