Thermostat Testing

Thermostat Operation Testing

Water In Tank Is Cold With Power ON.

1.This procedure assumes line voltage, ECO and elements are in working order.

2.Turn power “ON” to water heater.

3. Set multi-meter to “Volts AC”.

4. Check across terminals L1 & L3 of thermostat (see illustration 8)

A) Rated voltage NOT present, Check fuses.

B) Rated voltage IS present, proceed to next step.

5. Check across terminals L4 and T2 of thermostat (see illustration 9).

A) Rated voltage NOT present, Recheck ECO. If ECO is okay, replace thermostat.

B) Rated voltage IS present, okay thermostat is calling for heat, proceed to next step.

6. Check across element terminals (see illustration 10).

A) Rated voltage NOT present, check wire connections from thermostat to element.

B)Rated voltage IS present, Repeat element testing see page 11.

WARNING

High voltage exposure. Use caution to avoid

personal injury during this procedure.
