reinstall the heater and
pay attention to the key
points below
Tip 1

wires of the heater while
installing the new heater.
CHECK AND TEST 3
Step 1
Set multimeter to
resistance gear.
Step 2
Put detector into one
end of wires in PCB area.
Put another detector into
end of wires behind air
duct.
DIAGNOSIS 3
CHECK AND TEST 4
Step 1
Power on the appliance,
and press the button on
