Install Instructions For Harman Replacement Hose For The Differential Pressure Sensor Switch: 1-00-5113574
The switch is located in the rear of the stove. There is a white wire coming from the controller to one side of the switch and there are two light blue wires connected at the terminal on the other side of the switch. These light blue wires run to the igniter and to the feed motor. To change the switch, disconnect the white wire and double blue wires from the switch, disconnect the air tube, replace the switch and then connect the wires and tube back to the switch.
Troubleshooting
If the stove is not feeding and you are getting a vacuum error, 99.99% there is usually nothing at all wrong with the switch. The switch is simply sensing an airflow problem and is doing the job it was designed to do. The switch is normally open, which means no power can flow through the switch until the switch senses enough airflow to close the contacts.
The most important thing to know about the pressure switch is:
if there is a problem with the switch, the stove's feed system will not dispense pellets because the auger motor is not getting power.
unlike most brands, there is no vacuum error code on Harman Pellet Stoves
Common things that cause the switch to remain open are:
Excessively Dirty Stove
Clogged vent
Burnt out of worn out combustion blower
Door Gaskets: poor seal on stove door or ash pan door
Door Handle: Handle mechanism is broken and the door cannot close properly
Bad Hopper Gasket
Missing hardware or broken latch on hopper lid
Ash pan must be in stove to create proper air flow
Combustion motor cover must be installed and seated properly
Fines collection box cover must be installed and tightly sealed
Units with a hopper lid switch, the switch can fail
Units that take the pressure reading from inside the hopper (early versions of the XXV, Accentra and Accentra Insert) can have a broken filter at the end of the vacuum hose or the vacuum hose may have fallen off the end mount
Accentra Inserts - Hopper lid can be hinge bound and not seating

Very fast shipping, I had questions regarding the correct parts for our stove and was answered very quickly. I have not had the opportunity to install any of the new parts yet but will leave additional feedback after doing so.
I would definitely recommend Grill and Stove Parts to anyone I know that might need parts.
