|
| ||
| sure motor air intake is not blocked. 2. Disconnect thermal device connector from control | ||
| If sprayer still does not run, follow | board socket. Make sure contacts are clean and | |
| Step 1. | secure. | |

| 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). | |
