![2-13. DRAIN MICROSWITCH](/images/new-backgrounds/64331/6433161x1.webp)
| Model OFG- 390 |
| Upon pulling out on the drain handle, the microswitch should |
| be activated and the unit will not heat, but when the handle is |
| pushed back, the unit should operate properly. The bracket on the |
| microswitch is slotted so it can be adjusted backward or forward. |
| 1. Remove electrical power supplied to the unit. |
| To avoid electrical shock or property damage, move the |
| POWER switch to OFF and disconnect main circuit |
| breaker, or unplug cord at wall receptacle. |
| 2. The following check should be made to determine if the |
| drain switch is defective. |
| a. Remove bracket from the unit. |
| b. Remove wires from the switch. |
| c. Check for continuity across the two outside terminals |
| on the drain switch. If circuit is open, the drain switch |
| is bad. The circuit should only be opened by pressing |
| on the actuator of the drain switch. |
| 3. To replace switch, remove switch from the bracket, and install |
| switch in reverse order. |
| 4. Test to see if drain valve handle actuates the switch. The gap |
| between the drain switch and the shaft should be no more than |
| 1/8” (3 mm). |
| NOTE: Listen for click of switch while pulling drain |
| valve handle. |
