At the main disconnect switch, place one meter lead on the
phase that connects directly to the heating element. Place the
second meter lead on the line side terminal of the circuit
breaker for the phase that connects to the SSR. Measure the AC
voltage across the two phases.
Does the voltage correspond to the voltage printed on the
serial number tag?
No
Repair or replace the wiring from
the main disconnect switch to the
circuit breaker for the phase that
connects to the SSR.
Yes
At the main disconnect switch, place the meter lead on the
phase that connects directly to the heating element. Place the
second meter lead on the load side terminal of the circuit
breaker for the phase that connects to the SSR. Measure the AC
voltage across the two phases.
Does the voltage correspond to the voltage printed on the
serial number tag?
No
Reset or replace the circuit
breaker.
Yes
At the main disconnect switch, place the meter lead on the
phase that connects directly to the heating element. Place the
second meter lead on the line side terminal of the chamber
high limit for the phase that connects to the SSR. Measure the
AC voltage across the two phases.
Does the voltage correspond to the voltage printed on the
serial number tag?
No
Repair or replace the wiring from
the circuit breaker to the chamber
high limit.
Yes
At the main disconnect switch, place the meter lead on the
phase that connects directly to the heating element. Place the
second meter lead on the load side terminal of the chamber
high limit for the phase that connects to the SSR. Measure the
AC voltage across the two phases.
Does the voltage correspond to the voltage printed on the
serial number tag?
No
Reset or replace the chamber high
limit.
Yes
At the main disconnect switch, place the meter lead on the
phase that connects directly to the heating element. Place the
second meter lead on the L1 terminal of the SSR. Measure the
AC voltage across the two phases.
Does the voltage correspond to the voltage printed on the
serial number tag?
No
Repair or replace the wiring from
the chamber high limit to the SSR.
Yes
Is the LED illuminated on the SSR?
No
Refer to the topic Chamber do not
Heat - Element Line Voltage.
Yes
At the main disconnect switch, place the meter lead on the
phase that connects directly to the heating element. Place the
second meter lead on the T1 terminal of the SSR. Measure the
AC voltage across the two phases.
Does the voltage correspond to the voltage printed on the
serial number tag?
No
Replace the SSR.
Yes
