How To Make Sure Of Wireless Remote Control - Mitsubishi Heavy Industries SRR25ZJ-S Technical Manual

(C) Power transistor inspection procedure
[Use a tester with a needle indicator for the inspection. (Do not use a digital tester. Check in the AC 300 volt range.)]
(1) If there is a self-diagnosis display, inspect the compressor system (burns, wiring mistakes, etc.) If no problems are found, check
the output of the power transistor
(2) Output inspection procedure
Disconnect the terminals for the compresseor.
If an output such as the one shown in the figure on the below can be measured, the power transistor and the circuit board for
the outdoor unit are normal.
