Fresh food compartment defrost part error

From Service Manual 432059, p.31:

1.After separating MAIN PCB CN70/CN71 from PCB, check resistant value between CN70 brown and CN71 Orange; should be 102(220) ohm ±7%.

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.
