The White-Rogers digital thermostat uses the latest technology of a solid-state microcomputer to offer precise time and temperature control in your house. It is more flexible and can give you the heating and cooling options that fit your needs.
But in some cases, you may encounter an issue with the thermostat whereby it stops working or the voltage spikes. When that happens, the first thing you should do to troubleshoot the problem is to reset your White-Rodgers thermostat.
But Emerson/White-Rodgers thermostats come in different models. That means each unit has a slight variation in the reset procedure. Also, there is no reset button on a White-Rodgers thermostat that you can use to simplify the process.
You can start by referring to the user manual on resetting your specific device. Once you reset the thermostat, you can begin programming it again. We’ve explained below how to reset different White-Rogers models.
When to reset an Emerson thermostat?
A reset is necessary if you notice the following:
- A voltage spike
- A static discharge blanks out the display
- Erratic thermostat operation
- No Heat, No Cool, or No Fan
- Heat, Cool, or Fan runs constantly
But not all instances require you to reset the unit. Solutions could be as simple as changing the batteries or as complex as calling a technician for further assistance.
Here are a few and the best causes of action to take:
- Blank display and keyboard not showing: Replace batteries and check heat/cool system for proper operation.
- The thermostat does not follow your program: Check your current clock and program settings.
- Heat, Cool, or Fan runs constantly: Start by checking each wire connection to verify they are not shorted or touching together. You may have to contact a technician if the condition persists.
- The thermostat produces no heat and no Pilot light: Re-light pilot light.
- The thermostat setting and thermometer do no align: Adjust the thermostat thermometer settings to +/- 4 degrees.
Some issues are so complex that they require you to service the cooling system or replace the thermostat. If you also notice a possible short in the thermostat, wiring, heat, cooling, and fan system, contact a technician or the manufacturer for further assistance.
