Ohm Ice Thickness Probe

NOTE:

Verify meter leads are properly connected to

VOM with the red meter lead connected to positive &

the black meter lead connected to negative

•

Disconnect Ice Thickness Probe from control

board

•

Connect red meter lead to the red wire and the

black meter lead to the black wire - Normal

readings = 1.4 to 2.5 KΩ's.

•

Reverse leads - Connect black meter lead to the

red wire, red meter lead to the black wire - Normal

readings = 1.2 to 1.5 KΩ's.

Check control board voltage

•

Set VOM to DC voltage scale - Check voltage

across the top and bottom pin - Normal readings =

3.25 to 3.35 VDC.

Pass Ohm values are within range - Check control board

voltage at the ice thickness probe connection.

Fail

Replace ice thickness probe.

Pass Control board voltage is normal

Fail

Replace control board
