| Component | Test Procedure | Check result | Remark |
|---|---|---|---|
| 1. Thermal cut off | Measure resistance of terminal to terminal | If thermal fuse is open must be replaced | Heater case-Safety, Electric type |
| 2. Hi limit Thermostat (Auto reset) | Measure resistance of terminal to terminal | Resistance value ÷ ∞ | Heater case, Hi limit, Electric type |
| 3. Outlet Thermostat (Auto reset) | Measure resistance of terminal to terminal | Resistance value ∞ | Blow housing Safety, Electric type |
| 4. LED Lamp | Schematic | If the lamp is turned on by connecting is normal. | It is not measured by multimeter because Vth is 3.2V |
| 5. Door switch | Measure resistance of the following terminal | Door open: COM - NC (1-3) Resistance value < 1Ω; COM - NO (1-2) Resistance value ÷ ∞ Door closed: COM - NC (1-3) Resistance value ∞; COM - NO (1-2) Resistance value < 1Ω |
|
| 6. Idler switch | Measure resistance of the following terminal: COM - NC | 1. Lever open: Resistance value < 1Ω 2. Lever push (close): Resistance value ÷ ∞ |
|
| 7. Heater | Measure resistance of the following terminal | ① Terminal: 1 (COM) - 2: 10Ω ② Terminal: 1 (COM) - 3: 10Ω ③ Terminal: 2 - 3: 20Ω |
Electric type |
| 8. Thermistor | Measure resistance of terminal to terminal | Resistance value: 10Ω | Heater case - Hi limit, Electric type |
| 9. Motor | Measure resistance of the following terminal | See Page 21 | |
| 10. Gas valve | Measure resistance of the following terminal | Resistance value: > 1.5~2.5 kΩ | Gas type |
| 11. Igniter | Measure resistance of terminal to terminal | Resistance value: 50~800 Ω | Gas type |
| 12. Flame Detect | Measure resistance of terminal to terminal | ① Open at 370°F ((Maximum): Resistance value ÷ ∞ ② Close at 320°F: Resistance value < 1Ω |
Gas type |
| 13. Outlet Thermostat (Auto reset) | Measure resistance of terminal to terminal | ① Open at 203 ± 41°F (95° 5°C): Resistance value ∞ ② Close at 158 ± 41°F (70±5°C): Continuity < 1Ω |
Gas type, Gas funnel |
| 14. Outlet Thermostat (Manual reset) | Measure resistance of terminal to terminal | ① Open at 230 ± 41°F (110 ± 5°C): Resistance value ∞ ② Manual reset: Continuity < 1Ω |
