Cubed ice maker water pipe heater circuit fault

From Service Manual 970789, p.41:

1.Separate MAIN PCB CN20 wire, measure resistance between CN20-"19" ↔ "23"; should be 72 ohm ±7%. 0 ohm = heater short, infinity = wire/bimetal open.

2.Measure the heating element resistance across the terminals with the leads removed. Expected: 11 to 13 ohms.

3.Verify the thermal fuse and high-limit thermostat show continuity. An open safety in series with the element produces a no-heat fault even when the element tests good.
