Safety

Electricity power is still kept in capacitors even the power supply is shut off. Do not forget to discharge the electricity

power in capacitor.

Electrolytic Capacitors

(HIGH VOLTAGE! CAUTION!)

Connect discharge resistance (approx.100

Ω

40W) or soldering iron (plug) b, - terminals of the electrolytic

capacitor on the contrary side of the outdoor PCB.

Note: The picture above is only for reference. The plug of your side may be different.

Main parts check

1. Temperature sensor checking

Disconnect the temperature sensor from PCB, measure the resistance value with a tester.
