Harman accentra 52 non insert help with distribution fan(and/or a source for a service manual)

[idiggplants]

long story short: need a manual and/or guide on how to diagnose different things on this unit, primarily the safety switches and distribution fan.

long story long:
some backstory:we have a classic bay 1200 that i know inside and out. beyond that, I dont have a clue about how other pstoves work, including harman's. this is my MILs pellet stove. her and her dude bought it used from some shadeball. dude she was with was legit slow. like, legit off his rocker, special slow kind of guy. no shade in his direction but i dont trust anything he did. she is no longer with the dude. so basically im coming in with zero real knowledge of the thing, and im trying to teach her how to use it and also make sure it wasnt rigged up.

where im at now:

1. from what i can tell this thing has a non-functioning distribution fan. Almost zero air coming out of it, plenty of (very hot) air going outside. the stove gets extremely hot, including in the pellet box. the exhaust air is extremely hot as well. i would assume that the way i diagnose if the distribution fan is bad would be to see if it is getting 110v to it. but is there a firebox sensor that kicks it on when it gets up to temp? or does it get 110v right from the beginning? with my 1200, i know that at these temps it is getting up to would kick in a safety and shut the auger down. im shocked that this one doesn't, which brings me to my next point...

2. i have zero confidence that the shadeball they bought it from(or the idiot dude) didnt bypass safety items to get it running.

3. i cant source a service manual for the thing. seems like 90% of these were inserts. and im not sure how much changed over the years. im very capable of running tests on the thing to confirm the fans, and other things are functioning, but i need a manual. this is the one i found on the harman website, but im not sure if it is the right model. it doesnt seem to have any diagnostics for the stove at all other than the basic "if its not lighting, make sure this is clean" type of stuff. do they make a separate service manual? im looking for things like... bypass snap #1, test resistance of this, such and such.

4. misc stuff. looks like below the info plate on the back there is a 2 lead attachment point. is this where i would attach the room sensor? and its that simple, no other parts necessary? im happy to get a general crash course on this thing. for now i just want to get it operating correctly, but eventually id like to learn how to clean it so i can teach her how to do so correctly.

i can get more pictures to narrow down the model if necessary. forgot to get one of the control board.

a million thanks folks!

thanks so much. so the only issue is... there is essentially zero info on parts, or electrical diagram, or anything to self diagnose beyond what is on page 21, which is essentially "flame to low? turn up feed rate." type of nonsense.

is there anything that would show me the electrical diagram, or a step by step true diagnostics thing? i found one for the newer insert model, but im not sure if that would be the same as this model.

https://downloads.hearthnhome.com/installManuals/ACC52i_I.pdf

based on that it looks like there are only 2 sensors. the vac sensor, which controls the auger as well, so i know that is good, and the esp, which i know it reads the exhaust temp and then gives that info to the control board, but im not sure what it does with that info. could that be too dirty or bad that its not telling the control board to turn on the distribution fan? maybe? shame the manual isnt as descriptive as the cb1200 which basically lets you cancel out each part as the cuplrit one at a time.

so it might be the esp probe, might be the control board, might be the fan. my plan is to go over there, clean the esp, and then turn on the thing and see if it has 110v to the fan. if it does, the fan is bad, if it doesnt its either the esp or the control board....

or im misinterpreting the manual, or reading the wrong manual! lol

Good information on this thread. Not sure if your stove has stove temp settings called constant temp on some stoves: Stove Temp has 2 unique working modes - Auto and Manual via igniter switch selection. Stove temp AUTO will allow the distribution fan to run at most temperatures selected. Stove temp MANUAL will turn off the fan unless the temp knob is 5 or HIGHER to prevent the stove from overheating I would presume. Harman calls this "Fireplace mode" or something like that, to have a large flame without overheating the room

Diagram may or may not be for your year stove also diagram at end of attached manual. Some manuals have diagrams some do not.

To help everyone with part numbers and to keep the repeated posts about looking up part numbers (like that will stop anyone). I have attached the electronic part's numbers. Remember this stuff is top secret and for Harman stove owners only. If a non-Harman stove owner reads this I will unleash SeAL team 6 on your non Harman stove owner butt. Be ready.

great info. thanks! i was just reading that "what your manual doesnt tell you" thread. still have a ways to go.

few more things ive noticed. i havent found a wiring diagram that has a "hi/low" switch like this model has.

will have her send me a picture of the control board when she gets home. good to know on manual mode. i guess that may have kept it from running the distribution fan, although i have to imagine with how hot it was it would have been kicking on.

current plan is to go over there tomorrow and clean the thing out real well, including the esp probe. check to see if the fan moves easily or if it is binding or has a bad bearing. check if the thing ever sends power to the fan. then go from there and decide if i should order a new fan, or something else.

ohh, one other thing i noticed... while that manual is titled as the freestanding accentra, if you look on the last page the wiring diagram calls it out as a diagram for the absolute, allure, xxv-tc, and accentra 52i(insert) models.

the main thing i am getting from this, though, is just about everything is looking the same, minus the number/style of blowers... which is pretty unimportant. and its looking like im prepared enough to get the job done. so i thank you both! ill report back after i get over there.

When you’re ready to clean it out, this will work amazing if you have one with the vacuuming option…leave the door open so you don’t damage the vacuum switch and if you have an air compressor with a fine point nozzle to use in the firebox it cleans it even better…there’s also a small plate under the burnpot held on by 2 wingnuts, clean in there too all done cold and with the stove unplugged

Your stove is the Accentra FS (freestanding) manufactured May 2003. The dimples in the month and year are shown in your picture #4. I've attached my manuals if it helps.

First things first I would run the test mode on it which will turn on all the fans. Then go from there.

ohh man, thank you so much. this pretty much gets me everything i need!

to be honest, there is a chance she had it set to the "fireplace mode" and didnt realize it. she doesnt have a room sensor(i will be getting her one), and she had to set it to manual mode because her ignighter isnt working. she probably had it set to below 5 on the heat output because it isnt a big place.

between knowing that test mode will force the blower on, and some basic diagnostics, and a deep cleaning i think ill have her up and running. she probably hasnt had a clue how to clean it, either. cant ever hurt to get brownie points with the MIL!

thanks again!
