RESISTANCE SENSOR TEMP FLOW AND HARNESS

Isolate Mains Power to appliance as per TOPs P4

Set Multimeter to Resistance

Gain access to PCB
Disconnect plug X7 from PCB

Measure resistance across pin 3 (pink) and pin 4 (black) on connector X7.

Resistances vary with temperature and should conform approximately to the table below:

Note: Clicking on the resistance table will switch between table and graph view.

Note:
Wires may be multicoloured.
