| Component | Test Procedure | Check result | Remark |
|---|---|---|---|
| 1. Thermal cut off | Measure resistance of terminal to terminal | ① Resistance value ≒ ∞ ② Continuity (250°F ↓ ) < 1Ω |
• Heater case-Safety • Electric type |
| 2. Hi limit Thermostat (Auto reset) | Measure resistance of terminal to terminal | ① Resistance value ≒ ∞ ② Resistance value < 5Ω |
• Heater case - Hi limit • Electric type |
| 3. Outlet Thermostat (Cut off) | Measure resistance of terminal to terminal | ① Resistance value ≒ ∞ ② Resistance value < 5Ω |
• Blower housing - Safety |
| 4. LED Lamp | Schematic: 12V IN, LED ASM, DI, R1, LED1, LED2, 68R/J(1W) | If the lamp is turned on by connecting is normal. | It is not measured by multimeter because Vth is 3.2V (except for DLE3600*, DLG3601*) |
| 5. Door switch | Measure resistance of the following terminal 1) Door open 2) Door closed |
