| We have a 4" system and have struggled for years. We went from 15 hp to 20 hp and still it didn't help much.
Ultimately we found that the breaker for the blower had loose wires. I tighten the lugs down as hard as I could and still could pull the wires right out, so we replaced the lugs then the next year the whole breaker.
Also we had assumed that our system was plugging because we were running it too hard. Actually we had a loose relay in the airlock, when it would trip it would shut everything down through the safety circuit and backup the blower. The air system doesn't show up in my dryer safety circuit diagnostic board so it was really difficult and took years to diagnose the loose relay. | |
