: Thermocouple testing
Disconnect the plug J1 from the board TH 43 and measure the resistance of the thermocouple
with a digital multimeter, range 100 Ohm.
The resistance must be very low, about 0,5 Ohm.
If the resistance is very high or infinite, then the thermocouple is faulty and must be replaced.
