Enviro EF-II I technical manual The stove will not shut down, The stove keeps going out

POTENTIOMETER READINGS:
Full clockwise (switched off) = open circuit, overload or infinite resistance
LOW FIRE	800K OHMS to	900K OHMS
HIGH FIRE	68K OHMS to	82K OHMS

-If the range does not vary or the switch does not close then replace the potentiometer.

8)The stove will not shut down

-Make sure the auto/manual switch is in the auto position.

-Check the connections to the 120°F (49°C)-N/O temperature sensor and the auto/manual switch against the wiring diagram.

-Check the 120°F (49°C)-N/O temperature sensor by removing one of the brown wires from the sensor. The unit should shut down right away as long as the switch is in the auto position, if this happens Replace the 120°F (49°C) –N/O sensor. If the stove does not shut down then test the switch.

-To test the switch, the stove must be cold. With one of the brown wires removed from the 120°F (49°C) N/O temperature sensor, remove the gray wire from the switch, the stove should shut down. If this is the result then replace the auto/manual switch.

-If the stove still does not shut off, replace the wiring harness.

9)The stove keeps going out

-If the stove goes out and leaves fresh unburned pellets in the burn pot liner, the fire is going out before the 120°F (49°C) –N/O temperature sensor shuts the stove off

-Check to see that the slider damper is in the correct position

-Turn the Dial-A-Fire up slightly (poor quality pellets will require a slightly higher setting)

-If the stove goes out and there are partially burned pellets or cigarette like ashes left in the burn pot liner, the stove shut down due to lack of air, exhaust temperature or a power failure.

-Adjust the slider damper

-Check to see if the stove needs a more thorough cleaning.

-Turn the Dial-A-Fire up slightly

-Did the power go out?

-If the stove goes out and there are no pellets in the burn pot liner, the auger is stopping.

-SEE: “The auger motor will not function normally” and “The exhaust blower will not function normally”.

10)Ignitor will not function normally.

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

-Make sure the burn pot liner is tight against the ignitor tube.

-Check all the electrical connections to the 120°F (49°C) temperature sensor located on the exhaust channel

-Check the connections at the igniter socket.

-Place a jumper wire between the two leads on the 120°F (49°C) temperature sensor. If the igniter works. Replace the sensor

-If the igniter does not work. Replace the igniter.

NOTE: The igniter should be a bright yellow or bright orange in color. If not Replace the igniter.
