Signs it’s time to replace

  • Water gets scalding hot or never gets warm
  • Heater won’t start and the ECO (high-limit) has tripped
  • No continuity across the thermostat when cold

Tip: Gas-side (12V) and electric-side (120V) thermostats are different parts. Check which side has the problem.

Guide: Electric side not working: element, thermostat, ECO, switch
