I took my RH temp blend motor out today, well the dist blend motor above it too.
The reason was to check the flappage for jams, however the flaps move freely which is a start.
The motor seemed to not turn but I applied some volts directly to it on the brown and black wires and it turns, but it is a little lumpy in turning.
Opened up and cleaned and it is a little better. I cannot see any missing teeth on the gears but it is not smooth running. If I run it without the small gear mounted on the pot then it turns smoothly and behaves. Cleaned the pot with switch cleaner, no different.
I see you can get the pot, but that seems ok with a meter on the wiper and either end so suspecting a gear issue as they do not look ok. Arrows are aligned on the main gear (with the indexing flat on it) and the pot gear.
Can you purchase replacement gears separately? or best just go for a new/used motor? I see some on that auction site for about a tenner each.
Thinking of swapping my dist motor into the position for now to prove a point to myself..........
Opinions?
Cheers
