1. Introduction
This manual provides essential information for the safe and effective installation, operation, and maintenance of your Everbilt T-O-D Style Upper-Element Thermostat. This thermostat is designed for use in residential electric water heaters, specifically those with a non-simultaneous heating design where only one heating element operates at a time. Please read these instructions thoroughly before proceeding with installation or use.
2. Safety Information
WARNING: Risk of Electric Shock and Burns.
- Always disconnect power to the water heater at the circuit breaker or fuse box before attempting any installation, maintenance, or inspection.
- Ensure the power supply is locked out and tagged out to prevent accidental re-energization.
- Installation and servicing should only be performed by qualified personnel familiar with electric water heater systems and electrical safety procedures.
- Wear appropriate personal protective equipment, including safety glasses and insulated gloves.
- Do not bypass or modify any safety features of the thermostat or water heater.
- Ensure all wiring connections are secure and comply with local electrical codes.
3. Product Overview
The Everbilt T-O-D Style Upper-Element Thermostat is a critical component for controlling the temperature of the upper heating element in a two-element electric water heater. It features a temperature adjustment dial and terminals for electrical connections.

4. Installation
Before beginning, ensure all power to the water heater is OFF at the main electrical panel.
- Disconnect Power: Turn off the circuit breaker or remove the fuses supplying power to the water heater. Verify power is off using a voltage tester.
- Access Thermostat: Remove the access panel(s) on the water heater to expose the thermostats and heating elements. You may need to remove insulation.
- Remove Old Thermostat: Carefully disconnect the wires from the old upper thermostat, noting their positions for correct re-connection. Remove the old thermostat from its mounting clips.
- Install New Thermostat: Insert the new Everbilt T-O-D Style Upper-Element Thermostat into the mounting clips, ensuring it sits flush against the tank.
- Reconnect Wiring: Connect the electrical wires to the new thermostat terminals exactly as they were connected to the old one. Refer to the water heater's wiring diagram if unsure. Ensure all connections are tight and secure.
- Set Temperature: Adjust the temperature dial on the thermostat to your desired setting. A common setting is 120°F (49°C) for energy efficiency and safety.
- Replace Panels: Replace any insulation and the access panel(s).
- Restore Power: Turn the power back on at the circuit breaker or fuse box.
- Test Operation: Allow the water heater to heat up and check for proper operation.
5. Operation
The Everbilt T-O-D Style Upper-Element Thermostat works in conjunction with the lower thermostat in a non-simultaneous electric water heater system. When the water in the upper portion of the tank cools below the set temperature, the upper thermostat activates the upper heating element. Once the upper portion of the tank reaches the set temperature, the upper thermostat deactivates the upper element and allows power to flow to the lower thermostat, which then controls the lower heating element.
To adjust the water temperature, rotate the dial on the front of the thermostat to the desired setting. The red button on the thermostat is a manual reset button for the high-limit switch. If the water temperature exceeds a safe limit, this switch will trip, cutting power to the elements. If tripped, allow the water heater to cool, then press the red button to reset.
6. Maintenance
The Everbilt T-O-D Style Upper-Element Thermostat generally requires minimal maintenance. However, periodic inspection is recommended:
- Annual Inspection: Annually, with power disconnected, remove the access panel and visually inspect the thermostat and wiring for any signs of corrosion, loose connections, or heat damage.
- Cleanliness: Ensure the area around the thermostat is free from dust and debris, which could impede heat transfer or create fire hazards.
- Reset Button: If the high-limit reset button trips frequently, it may indicate an underlying issue with the water heater or thermostat. Consult a qualified technician.
7. Troubleshooting
If your water heater is not functioning correctly, consider the following common issues:
| Problem | Possible Cause | Solution |
|---|---|---|
| No hot water | No power to water heater Tripped high-limit switch Faulty upper thermostat Faulty heating element | Check circuit breaker/fuses Press reset button on thermostat Test thermostat (with power off) Test heating element (with power off) |
| Insufficient hot water | Thermostat set too low Faulty upper thermostat Faulty heating element | Adjust thermostat setting higher Test thermostat (with power off) Test heating element (with power off) |
| Water too hot | Thermostat set too high Faulty thermostat | Adjust thermostat setting lower Test and replace thermostat if necessary |
If troubleshooting steps do not resolve the issue, it is recommended to contact a qualified appliance technician or plumber for further diagnosis and repair.
