Thermostat Replacement in Attleboro, MA

Electric water heaters rely on upper and lower thermostats to keep water at a safe, steady temperature. When a thermostat sticks or fails, you get cold showers, overheating, or a unit that constantly trips its reset button — sometimes with weeping at the element gaskets from thermal stress. We test both thermostats and replace the failed one with a correctly calibrated unit.

Older electric heaters in Attleboro's vintage homes often run original thermostats decades past their prime, and past DIY electrical work in these houses sometimes leaves mismatched parts behind. We verify the whole control circuit — thermostats, elements, and wiring — so the new thermostat isn't compensating for a deeper electrical issue hiding in an old panel or junction box.

How We Handle It

1. Power down at the breaker and verify zero voltage before touching anything.
2. Test upper and lower thermostats plus both elements to isolate the failure.
3. Install the new thermostat, set to a safe 120°F, and check wiring connections.
4. Restore power, confirm even heating cycles, and check for leaks at the element gaskets.
