My in-laws have an - I'm going to call it an antique - Kenmore dryer. They bought it in 1957 had have been using it regurarly since then.
It's electric, running on 220V, and blows it's internal circuit breaker within a couple of minutes of turning it on.
I fixed another problem they were having with it maybe 3 months ago. One of the V belts came off (the bigger one), the main drive pulley was loose, and the bearing was shot.
I pressed a new bearing into the pulley and shaft assembly and put it back together with new belts. I used a sintered brass bearing. It it seemed ok and was running true when I left. Almost immediately it had problems, and when I went over the following week it had destroyed itself - it was actually pulverized. It turned into a small hand full of bronze powder on the floor inside the unit.
I put in another bearing, this time a Glass-Filled PTFE bearing. It was a lot easier and it works a whole lot nicer.
NOW, the problem is that the circuit breaker trips and shuts the dryer off within about 3 minutes after starting it. This is a round breaker just inside the lint trap door on top of the machine. Is there any way I can test the breaker? How easy is it to replace?
Any help diagnosing why it trips would be appreciated.
