Trouble shooting chart

Remote reception is insensitive or fails.

Remote reception is
insensitive or fails.

Yes

Check if the remote control
works properly.

Check if the power supply
voltage to the remote sensor
is normal.

Use an oscilloscope to check if there
is output waveform from the first pin
IR of the remote sensor after pressing
button on the remote control.

Check if there is IR signal
on pin G5 of IC4001.

Check battery.

Check R103 or replace Front PCB.

IC100 (PIN1 - RC waveform)

Change IC4001 or replace Main PCB.

IR waveform

Correct connection.
