Hello, this is my first post and it’s a long one. My wife and I had a Accentra 52i-TC professionally installed late October 2025. It is my first pellet stove after suffering through a 1986 Vermont Castings Defiant Encore wood stove that couldn’t burn more than 4 hours. I’m not entirely in love with this new pellet stove but I’ll cover that later.
The current problem with the pellet stove is that it will have a combustion fan RPM error intermittently. It started 5 days ago when I came downstairs in the morning to find the stove shutting down even though the room wasn’t up to temp. The error was displayed and there was no RPM reading BUT the fan was still operating. Air was being forced through the throat and the fire was not smoldering. I ate breakfast and came back to find it operating without issue, RPM reading was back.
The stove ran fine for 24 hours. I came home the following night and found that the stove had not run since the morning cool down cycle. The screen was showing the combustion fan RPM error and it would not fire. The stove was due for a complete cleaning right down to the day so I performed that full cleaning and rebooted the stove, but it still did not run.
My dealer came out the next day and did a few things to it, although I don’t know exactly what. The stove did not work that night or the next day.
The day after that, the dealer returned and said that Harman told them to replace the control board, the combustion blower and the wiring harness. The stove ran fine for more than 24 hours. Last night after the fire was out due to the schedule I went to scrape the throat and the screen displayed the combustion fan RPM error once more! I did not have my phone on me so I went to get it to take a picture for the dealer but by the time I got back to the stove the error had cleared. When the error was displayed there was still air being forced through the throat.
Today the stove fired fine on its own per the schedule and has stayed running. This problem is of course happening during one of the coldest stretches of weather we’ve experienced in a while.
I’d really like to know how the fan RPM sensor works. I’m an automotive technician with 20 years experience and I’m familiar with all types of sensors and their intermittent failures. I’d rather not have to put effort into fixing it myself since it’s under warranty but if they prove incapable of fixing it I may have to step in.
The stove is plugged into a Tripp-Lite APS750 that has a 100Ah AGM deep cycle battery for power backup and voltage regulation. We haven’t yet experienced a power failure (remarkable for our location) but the APS750 is supposed to provide stable voltage regardless of whether it’s brownouts or complete power failure.
Has anyone been here before? I am concerned I have a lemon stove on my hands. And this is not even considering the noises and vibrations this thing makes during “normal operation.” I also need an outside air kit next season. Thanks for your time and consideration.
