2004 New England 25-PDVC Running Fast/Hot

[Gigwam]

Hi,
This stove has been a total workhorse for us, and apart from a few motor replacements has been trouble-free. Checked the stove tonight and it seems to have taken on a mind of its own - feeding at a very high rate and burning hot even though set at 1-2. Manual settings (bottom 3 buttons) right now are 2-2-1, which is low compared to the 5-5-1 and 6-4-1 norms per other posts I've read on this year/model. Any ideas?

These control boards sometimes slip into the wrong mode. For the PDVC it should be in mode D. Mode C intended for the PDV has a higher fuel feed rate. I don't know about the other burn modes, I have heard of them changing modes by themselves. The usual complaint is that it happens after a power restart.
This should get you there:

Perform a Control Board Reset as follows .....

Do this when the stove is cold.
Unplug the stove from the power outlet.

Plug the power lead back in.

You must press and hold the bottom 3 buttons all at the same time within 4 seconds and wait 3 seconds and then release buttons.

Wait 5 - 10 seconds for the F5 readout display to go blank.

Unplug power lead - wait 5 seconds

Setting the Heat Mode
Heat Mode, the default setting is 'd' for the 25-PDVC, but some control boards default to 'A' when a reset is done. Do not run the stove in 'A' or 'b' mode.
Plug power lead back in and press both the up and down blower speed buttons at the same time within 4 - 5 seconds, you should now see a letter (A, b, c or d) in the left digital display under heat range, you need to change this to 'd' or 'c' using the up / down buttons below that readout, once set to 'd' or 'c' wait 10 - 15 seconds then unplug the power again and wait 5 seconds. (Sometimes the mode that you want does not set and defaults back to the mode that it was in before, repeat this step to make sure the mode that you want is set.)

Plug power back in, then set the lower three (3) buttons to read 6 4 1 from left to right.

Clean out the stove and reload with pellets and fire it up. Set the heat range to 2. Set the blower speed to 3 or 4 and then leave the stove alone for 60 - 90 minutes. After 60 - 90 minutes have passed, set the heat and blower to the numbers that you want.

Check the plate in the bottom of the hopper, it can move / bend and allow more fuel in. The larger the opening, the more fuel is dropped in.
