I have been having problems with the blower on my Harman PP38+, starting about halfway through last winter. It started with a loud intermittent screeching sound, that at first didn't seem to be connected to anything. Over time the sound became louder and more frequent, with a clear connection to the blower control. The stove was quiet while warming up, until the blower kicked on, and then the screeching would start. It increased in volume and intensity as the blower control knob was turned up.
Shortly after cleaning out the stove and turning it on this year, the noise became worse. The other day, the blower stopped kicking on entirely. The stove will turn on and keep burning, pellets seem to be feeding properly, and there is a little bit of warm air coming out, but the blower never kicks in. The blower control knob does nothing, except change the frequency of a low buzzing noise that the stove makes.
At this point, the stove is only heating a small area surrounding the stove, which is enough to keep the cat from freezing, but not to warm any of the house. I've stuck a fan next to it to spread the little bit of heat around the best I can, but I could really use some help figuring out how to fix the problem. I don't want to drop $200 plus parts and labor for a service call (that's the best deal I can find where I live), so any help is appreciated.
My best guess is the blower motor needs to be replaced. I believe I may need the part discussed in this thread:

Does anyone know if my problem is definitely the blower motor, or should I have it diagnosed before buying the part? If I do need that type of part, is there a similar one available cheaper? Also, how difficult is it to install a new blower motor? Thanks for reading this long post, and any help you can offer.
