I actually called and talked to the parts guy and he claims it's the right one. Like an hour ago. The tech is calling me Monday.

Yes, it is the same as you had before, but if they were nice, they would have provided the updated card.
re those dip switch settings, there are two control board versions listed, note yours for future reference, however the switch positions are the same

 

[Spaz]

That's right from the manual, if I'm reading it right it should stay running. You're saying the tech didn't configure it for a manual start?

Here's the box.

Here's the info off the sheet.

Good news I think. I went down and set my stove in room mode, igniter auto, then turned the temp dial down. The status light went out.

Do you remember the dipswiches? Review the chart again:

Harman Pellet Stove DIP Switch Settings Explained

If you own a Harman pellet stove, you may have heard about DIP switches. These tiny switches are located on your control board and act like the “settings menu” for your stove. They tell your stove how to ignite, how much fuel to feed, and even which temperature sensor (ESP probe) it should...

The two columns are for different ESP probes (colors of the wire) the other ones tell it there is no igniter.
You stove think's it has an igniter set to auto which is why it is shutting off.
However - the combustion blower should stay running until the stove cools.

Did it shut off or go down to ambers? It did it still have a flame?

I looked at my old one and didn't see any dip switches. I know that the part numbers are the same, but the new one has dip switchs

No not that - you don't have an igniter

Here's the rest of the picture. It says Manual ignition P61. So I'm not sure what you mean.

There's a better pic showing the configuration for a manual start P61. That's the new board. It's the same as the ones you posted.

Kind of hard to do when it's turned itself off.

That would be for the Red wire ESP. Do you have red or black? I forget. Unless it was replaced it would be black.
If you look at the top of the chart they have different settings for each type. The default is probably for red type.

Your old old board 33-20-05378 did not have dip switches.
To determine the dip switch setting for whatever card they installed, you need the ESP type, and the card part number
and possibly rev number.
To carry on with the troubleshooting the installed card needs to be looked at.
It is acting like is is set wrong. When you turn the dial down, the status light should stay on.

It does, it goes off when it hits the set point.

After more reading, I've come to the conclusion that I should either put the old board back in a try it to see if indeed does idle at the set temperature , or get a auto ignite board. I'm still waiting for some other gurus on the subject to get back to me. Also I've got the latest version of the board I can't find anything newer then revision E that I have. From the paper work I have that came with board it's the correct board and set correctly.

 

[Spaz]

Reading is good. The P38 (manual light) has same board with pin 8 being high instead. Setting max esp. Not sure to what value that would be. This revision is dated Jan 30 2017. And lastly, there's no mention of auto/ manual ignitor settings for the other pins.

 

[Spaz]

Here's the info sheet that I got with the board, it explains all the pins and what they do. Can some one point out the pin for auto/manual start setting? Pin 5 high means it's a red ESP. 1,2,3 are start up fed rates, see far left column .

It does, it goes off when it hits the set point.

It has been mentioned that people over think Harman stoves, and people want simple answers to their problems, so
I won't explain closed loop controls with reference and feedback ect, but turning the temp dial down when the room is hot
should produce the same result - the status light stays on, and the stove continues to run.

One other thing is that I have a manual/ auto switch I have to use on start up. I have to start it on manual, then switch to auto once it's running. I'm going to try turning it to manual on room mode and and see if it maintains heat.

Oh Shoot ! I didn't see that switch in the picture you posted the other day. I know we talked about you not having the Igniter light and switch, but that switch looks the same as my Igniter switch (Auto/Manual). You are in the Auto Igniter position right now. Flick it down and you will ne in manual lighting mode. Then it should stay running. It would have helped if there was label.
Look at the picture of Washup yesterday at 12:40pm

Edit - You will have the 4th LED light too but the guy never drilled a hole for it because you don't have the igniter. You do have the "new" version card

Well when it hits the desired heat, the distribution fan turns right off. It slows the feed rate right down. I'm not sure if it should be running with no fan running. When I turned it up the distribution fan come and it started feeding. I'm not going to go any further until I know if it's okay to run with out the distribution fan running. But it seems to be working.

In room mode, with that switch "up" "auto" when you reach the desired temperature the stove will shut off and the status light go out.
When you flick the switch down, and the room is hot enough, the distribution blower will shut off, the feed will be reduced, but the stove will stay on.
