hi i am dan i can help you with this. i am sorry if you have been waiting a while. i just logged on and saw your question now. usually with those thermostats dust builds up on the inside and affects them like that. if you would like to keep that thermostat then try blowing out the dust in it by removing the circle cover and use a dusting can to blow it out and clean it. if you would still like to replace it i would recommend going with a digital thermostat. any standard conventional thermostat will work. i would just recommend staying away from honeywell thermostats. if you have any more questions about this or if this answers your question please let me know
