Enviro EF2 owner manual Auger motor will not function normally

Troubleshooting

6. Everything else in the stove operates but the ignitor will not light the pellets.

wCheck the burn pot liner placement, the burn pot liner should be tight against the ignitor.

wCheck all the electrical connections on the 120°F (49°C) temperature sensor located on the exhaust channel.

wCheck the connections at the ignitor socket.

wPlace a jumper wire between the two leads on the 120°F (49°C) temperature sensor. If the ignitor works, replace the sensor.

wIf the ignitor does not work, replace it.

NOTE: The ignitor should be bright orange in color. If not, replace the ignitor.

7. The auger motor will not function normally.

wCheck for obstructions in the hopper system.

wCall your local dealer for service.

wMake sure the exhaust blower is operating.

wMake sure the dial-a-fire is turned on.

wUnplug the stove and open the side and back panels.

wCheck all the connections to the auger motor, auger dial-a-fire, vacuum sensor, 200°F (93°C) temperature sensor and the timing control module against the wiring diagram in this manual.

wCheck the condition of the vacuum hose (located on the left side of the stove). It should not be cracked or torn and should be installed on the top air inlet tube on the vacuum sensor.

wCheck the manual reset button on the 200°F (93°C) temperature sensor. If this sensor has been tripped, check for the cause of the over-heating before pushing the red button in. Check auger for movement.

wIf the auger still does not work, then apply 115 V AC directly to the auger motor. If the auger motor does not work, replace it.

wBy pass the 200°F (93°C) temperature sensor with a jumper wire; check the auger. If the auger works, replace the sensor.

wCheck the voltage across the load pins of the timing module. It should be around 1 V to 2 V AC, cycling to line voltage during an auger pulse. If not, replace the timing control module.

wCheck the vacuum sensor by placing a jumper wire between the blue wire and the black wire that are attached to the sensor. If the auger works, test to see if the exhaust blower is producing enough vacuum.

wTo test the exhaust vacuum, place a magnehelic gauge in the sensor end of the vacuum tube. It should read 0.5” W.C. If the reading is good, replace the vacuum sensor.

wIf the auger motor still does not work, then attempt to by-pass the auger dial-a-fire control by removing the leads from the timing control module’s second delay pins and placing a jumper wire across the pins. If the auger now cycles very quickly, test the dial-a-fire potentiometer. If the auger did not cycle, replace the timing control module.

wTo test the dial-a-fire potentiometer, the potentiometer should have a range of 68KΩ to approximately 850 KΩ (± 10%). If the range is not close, replace the potentiometer.
