FAULT FINDING
When using the fault finding flow charts, it is essential to ALWAYS start from the
beginning – the General Fault Diagnosis chart. Starting fault diagnosis from any
other chart is not correct usage and may result in misdiagnosis.
When measuring the resistance of a part, turn OFF the electric power and be
sure to disconnect the part completely before measuring (from connector or
terminal). Resistance checks are performed on the part while it is disconnected
from the controller.
“Live” testing to be conducted. Personal Protective Clothing (PPE) shall be
worn to reduce the risk of electric shock. Refer to Rheem Safety Procedure
on electrical testing.
CAUTION: Hot surface. Personal Protective Clothing (PPE) shall be worn to
reduce the risk of scalding. Be careful to avoid injury on sharp edges.
