Enviro 50-1574 Exhaust motor will not function normally, Light # 2 on Heat output bar flashing

Troubleshooting

üPoor Quality Fuel – Insufficient energy in the fuel to produce enough heat to keep the stove burning or operational.

üExhaust Temperature Sensor failure. – Bypass sensor located on Exhaust Blower if stove now operates properly, the unit may require cleaning or a new sensor. Contact your local dealer for service.

üCheck the fuse on the circuit board.

3. The exhaust motor will not function normally.

üOpen the left side access panel; check all connections against the wiring diagram. üSee “2. The stove will not operate when hot.” section.

4. Light # 2 on Heat output bar flashing

(The Vacuum Switch contacts have opened for more than 15 sec.)

üPinch, break or blockage in Vacuum Hose - Check hose for pinch points or damage, replace or re-route as required. Blow out Vacuum Hose

üBlocked Hose Barb on Exhaust Channel - Use a paper clip to clean out Hose Barb or remove the Vacuum Hose from the Vacuum Switch and blow into the hose to remove blockage.

üBlocked exhaust / venting system - Have stove and venting cleaned and inspected.

üSevere negative pressure in area where unit is installed - Check the operation by opening a window, does this solve the problem? If it does, install fresh air intake to unit or room. Venting system may require vertical section to move termination into a low pressure zone.

üVacuum Switch failure - Bypass the vacuum switch, if this corrects the problem check for above problems before replacing the Vacuum Switch.

üDamage to gray wires between Circuit Board and Vacuum Switch - Inspect wires and connectors

üCombustion Blower failure - The Combustion Blower is not turning fast enough to generate the proper vacuum in the Exhaust Channel. Visual Check; is the blower motor turning? Check the Exhaust Blower voltage across the blower wires (>=220V on #5 setting and >= 165V on #1 setting). – Replace the Circuit Board if the Voltage reading is less than 165 V. with a line voltage >220 V AC.

üCheck Vacuum levels in the exhaust channel by bypassing the vacuum switch, then remove the Vacuum hose from Vacuum Switch. Check exhaust vacuum readings by placing the open end of the Vacuum Hose on a Magnahelic Gauge. (readings must be above 24.9 Pa (.10” W.C.) on low fire).

If the motor fails to reach a 24.9 Pa (.10” W.C.) readings, then replace the Combustion Blower

To reset Circuit Board after a trouble code - push the ON/OFF button 5. Auger light flashes but auger motor does not turn at all.

üIf the Auger gear box does not turn but the motor’s armature does try to spin then the auger is jammed.

Try to break apart jam by poking at the jam through the drop tube. If this fails then empty the hopper and remove the Auger Cover **Remember to re-seal the cover after installation**

üCheck the fuse on the circuit board.

6. The 93°C (200°F) high limit temperature sensor has tripped.

üReset sensor and determine cause – was it Convection Blower failure or 71°C (160°F) Temperature Sensor failure? Bypass the 71°C (160°F) sensor, does the Convection blower come on high if not replace the blower? If yes, replace sensor (located on the left side of the firewall).

üCheck the fuse on the circuit board.
