6 times repeatedly |
| 3. Measure resistance of the thermal device. If reading | |||||||
|

|
|
| is not correct, replace motor. | ||||||
|
|
| Check Motor Thermal Switch: Unplug thermal | ||||||
|
|
| wires. Set meter to ohms. Meter should read the | ||||||
|
|
| proper resistance for each model (see table below). | ||||||
