Cordset Service
This part of Section 11 provides cordset‐related service procedures.
WARNING! Risk of personal injury or death. Allow only qualified personnel to
perform electrical installation, troubleshooting, or repair procedures. Before
performing any electrical procedure, review Section 1, Safety, and
disconnect and lock out electrical power to the system.
Checking a Heater
1. Disconnect and lock out electrical power to the system.
2. Disconnect the cordset that supplies power to the heater to be checked.
3. See Figure 11‐8, 11‐9, or 11‐10 as appropriate. Use an ohmmeter to
check the heater resistance and continuity at the heater pins on the
cordset:
S If you measure low resistance, the heaters are operating normally.
Return to the procedure that referenced this check.
S If you measure high resistance or if an open circuit is indicated, there
may be a broken wire, a loose connection, or a defective heater.
Continue to the next step.
