I'm not sure your problem is the same as mine, but I had an issue last year that had the same symptoms you describe. In my case, the problem was a side effect of interaction between the hysteresis of the otterstat switch and the effective setpoint of thermostat. The otterstat has a bit of hysteresis built in so that when it turns the fans on, the switch remains activated until the temperature comes down below a certain point at which time the switch opens. In my case, the thermostat was not performing properly and would not permit the temperature to come down low enough for the otterstat to turn off. In essence my thermostat was performing as if it had a setpoint too high. Replacing the thermostat solved my problem. You may be experiencing a similar issue, especially if you have an antique thermostat.
