Did you verify that the blower was or was not running in test mode prior to replacing it?
Are you getting the dhe code, either in or out of test mode?
The heater is controlled by a high limit cut out t-stat (thermal fuse), a high cycling t-stat and the low limit thermistor. The high cycle t-stat and thermistor tell the pcb if the heater needs to be on or off. To test the high cycle t-stat check for continuity at it's closed and open temperature ranges. You'll need to put it in an oven set for the open temperature. Take it out once the oven has reach the set point and check for a lack of continuity. Then as it cools off expect it to click and show continuity. It'll be hard to determine exactly what temperature it's cycling at but this will let you know it's working to some degree.
The spin speed can be determined in test mode. Refer to the test mode chart. Since it does not tell you what the rpm should be I have to guess. I've been doing it so long that I just listen to the pitch of the machine and can tell if it's off or not. Besides I've come to kinda distrust the info the pcb displays to me. I've seen it be incorrect to many times. All that being said, and based on another machines specs, I would expect to see the rpm read out at 125 - 155.
I have had to change the stator and rotor to solve a clothes too wet problem in wash only models before.
