Description

The function of the hopper lid switch is to cut the power to the feed system if the hopper lid is opened at any time during operation. This ASTM safety requirement of installing a lid switch was introduced to pellet stoves made in 2008. The rule was revised by ASTM in 2013 to allow manufacturers to forego the switch if the same safety function could be achieved in another way, which is why there is no longer a hopper lid switch on Harman pellet stoves made after 2013. Models equipped with this switch STILL NEED THE SWITCH to meet the ASTM safety standard.

Assembly Instructions For Harman 48" Hopper Lid Switch, 3-20-232108

Replacing the switch is different on various models. To access the gray cord which encases the two switch wires you will need to remove all of the pellet from the hopper to unfold the securing tabs and loosen the switch from the hopper mount. Disconnect the red and black wires of the switch cord from the wiring harness and pull the switch cord up and out of the hopper. The body of the switch will not fit through the wire opening and cannot be removed from the hopper from the bottom.

Install your new switch by passing the wires down through the hopper and out the opening, plug them in to the corresponding white wires, secure the switch to the top of the hopper and then secure the switch cord via the folding metal tabs.

Troubleshooting

The hopper lid switch is a basic interrupter switch, which is normally open and closes the circuit when the switch plunger is depressed. The wires for the switch are black and red and are wrapped in a gray rubber sheathing. The cord travels down the inside of the hopper towards the control board, exits the hopper and is connected to a white wire leading to the controller on one side and another white wire which is attached to the pressure switch. This circuit is the common return for both the feed motor and the igniter.


If your stove is not feeding or igniting at start up, try disconnecting the hopper lid switch from the circuit by plugging the two white wires together that are attached to each of the hopper lid switch wires. If your stove or insert resumes normal operation, replace the lid switch.


Newer stoves made ofter 2013 do not have a lid switch. Instead, the location on the stove from where the pressure switch monitors the vacuum pressure was moved so that if the hopper lid is opened, the feed system's power is cut. Harman realized that the pressure switch and the lid switch on the same circuit is a redundancy and were able to engineer the stove so that the pressure switch can meet the ASTM Safety Standards (achieve both functions) with only one switch.



Product Updates - Harman Technical Bulletin - August 2013


PELLET STOVE HOPPER LID SWITCH REMOVAL 

In the continual process of product improvement and compliance with current standards, all Harman pellet stoves will have the hopper lid switch removed from their designs by the end of June 2013. The removal of the hopper lid switch from the pellet stoves simplifies the wiring and construction of the unit while also making the stove easier to troubleshoot in the field. Although the switch is no longer an ASTM requirement, the hopper lid must still remain closed during normal operation to ensure safe, airtight conditions. All newer Harman products without this switch have been engineered to stop the feed cycle via a different process when the lid in open during operation.
