Harman Pellet Stove - What to do if Your Stove Will Not Turn Off
This is a common problem that many Harman pellet stove owners may experience from time to time and it can be very frustrating for the user. The problem presents itself usually one of two different ways; the stove is cold but power won’t turn off or the stove is warm and is continually feeding very slowly and will only shut down if it runs out of pellets.
Scenario 1 - Cold Stove, Won’t Turn Off When Powered ‘OFF’
The stove is cold. The MODE selection dial is set to OFF and combustion/ exhaust blower continues to run. On the control panel, the only lights that are illuminated are POWER and
COMBUSTION FAN. If you unplug the stove, the loss of power will cause the stove to turn off and if you plug it back in, the stove may remain off but when the MODE dial is turned the problem repeats itself or, in some instances the stove may enter right back into the error. Additionally, when this error occurs, the stove will NOT advance into the STARTUP mode either, pellets will not feed into the burnpot.
So, here’s what wrong; the pressure switch, commonly referred to as the vacuum switch, is not closing. When the MODE dial is turned from the OFF position, first in the order of operations, the combustion fan is powered up, which creates airflow through the stove. The pressure switch in the stove is here for this purpose, to detect this airflow. At startup, once his operation has been established or “proofed”, the controller detects the closed circuit from the pressure switch and moves to the next order of operation, which is fuel feed and igniter ON. If the pressure switch does not close or the controller does not receive the signal of the closed circuit, the stove will continue to run indefinitely. Additionally, the stove will also not shut off when the MODE dial is turned to OFF unless the pressure switch is closed.
Many folks that read the manual and are able to understand this concept are quick to think that the pressure switch is bad but that is rarely the case. In the hundred or so times I have encountered this problem, maybe once or twice has it actually been a faulty pressure switch so here’s what to look for.
Scenario 2 - The Stove Will Not Shutdown and Continues to Run until the Hopper is Empty
Harman Pellet Stoves are somewhat unique in their feed system design, unlike most pellet stoves that used a gravity feed system, in a Harman stove, the fuel is fed horizontally toward the fire and the coals actually sit behind a slight incline, which allows the fire to burn naturally from the top down. While this approach has many advantages with regards to efficiency and combustion flow, to prevent the fire from burning backward in the stove, the fuel must always be advancing forward, and this is true even during the shutdown process. To achieve shutdown, to get the fire to extinguish itself out, the fuel feed is slowed to 10% and very slowly the air overpowers the fire. When the exhaust sensing probe (ESP) in the stove senses a fall in exhaust temperature below 95°F, the controller cuts power to the stove and the stove will remain ‘OFF’ until a call for heat is initiated again. If the stove continues to run until the hopper is empty, here’s what to look for.

My serial number is WHI-009504/ P38+. Purchased summer 2006. Which control board would I purchase?
For Harman P38+ pre serial number 008190059 you will need 1-00-7738111 For a replacement control board. This an upgrade kit. Please see the description to see what the kit includes.
Can you fix the invincible t control board or what control board will fit ?
Hi,
The Invincible T control board has been discontinued, part number 3-20-00600. Harman is not distributing a replacement board for that unit. You may be able to take the board to your local electronics shop and see if it is something that can be repaired or replaced.
I have a P61A WHI-008291- Test date March 1998. The stove still works great but some of the functions are not working. I'm assuming it's the control board since they seem to work in test mode. What control board do I need?
This is the correct controller for all P61 pellet stoves WITHOUT auto-ignition. The correct controller for P61 stoves WITH auto-ignition is this controller.
FYI, P61-A, the "A" stands for Auto Ignition. Check your manual, the P61 was the only P Series with a currently supported controller that was available without auto-ignition. The P61-A has a higher serial number than yours, I think.
does it come with instructions for dip switch settings
Yes, it will come with instruction regarding what to have the dip switches set at according to what stove you have.
Perfect fit. Excellent quality. Make sure you pay attention to the dipswitch settings and read thoroughly and you'll have no problems
