Please bear with a short story here to explain my posting of this question, as I do not want anyone thinking I am out trying to put any HVAC people out of work ...
I had gone to the store to get some stuff for my bathroom project, and in the parking lot I happened to see an elderly woman I am inclined to help, and after she told me her furnace blower had quit working, I spent the rest of the day getting it going once again. She had called a regular furnance company, but when they saw her gas (Goodman) furnace sitting in her living room with no ductwork and an exposed exhaust going out through the wall about eye-high, they had many good reasons for turning away even though our temperatures around here have been single-digit for a couple of weeks now.
This was the dirtiest motor and blower I have ever seen, but I was able to get the assembly out without choking too badly -- four dead mice and a large nest went into the trash bin -- and everything actually cleaned up rather nicely. The only slippery substance immediately available was some cooking oil, and I used that to re-lubricate the wicked bearings after I had cleaned them up as best I could.
Sitting on the floor in front of the furnace, the blower assembly would not come up to speed unless I blocked its output about 50%, and after it was back in the furnace and the cabinet was closed up, I could still speed it up quite a bit by restricting one of the two registers in the plentum.
This capacitor-start motor has five wires: 2 black, 2 red, one yellow.
This motor is wired through what appears to be a small (Essex) controller that is about 3 inches long and 1-1/2 x 1-1/2.
My question is this: Does this woman have a weak motor, bad bearings dragging it down or a bad controller not bringing it up to speed?
She will definitely need a new motor before next winter, but I am hoping to help her get through another few weeks with this one.
I did a search but could not find this motor: GE 5KCP39HGM614S
