Hello
See error codes here from page 9 in the owners manual
Safety Features and warning code:
• Your heater is equipped with a temperature “high-limit” switch, designed to shutdown the auger in case of an over temperature situation. The high-limit switch is a thermo snap disc type and must be manually reset in the event of an overheat shutdown. Once the heater has cooled down, you can reactivate the high-limit switch by depressing the manual reset button located on the high-limit switch.
• When the High-Limit switch opens, which indicates an overheat failure, the HEAT LEVEL LED’s 3 & 4 will flash red.
• Your heater is equipped with a vacuum switch that automatically shuts down the auger in the event of a exhaust fan malfunction.
• When a Vacuum Error is sensed, the HEAT LEVEL LED’s 1 & 2 will flash red. Check to ensure the glass door is latched properly.
• When the Low-Limit switch opens, (fire went out) the HEAT LEVEL LED’s 4 & 5 will flash red. First check fuel supply, then check to ensure Auger is not jammed and finally that pellet hopper door is properly closed.
• When the Pellets in the Burn Pot fail to ignite HEAT LEVEL LED’s 1 & 5 will flash red.
See # 1 - You may have a worn or bad high limit snap disc. Press the reset button on the switch to reset and if the error persists then replace the snap disc with orange wire
