Question about Dryers
There are usually 2 thermal fuses in dryer circuits. One is on the
heater housing and will blow in an overtemp condition around 310-350F.
The other is on the blower or exhaust housing and will blow around 200F
Make absolutely sure the 2nd one is continuous and not intermittently functional. This will definitely stop the motor from functioning
Below is a diagram for an older model (LER4634). Your dryer has some additional terminals probably because it has additional drying cycle options.
The diagram may be more readable when copied and pasted into a plain text editor such as Notepad or another editor with non-proportional fonts
|TM |TM |BK |BK |BK |
|WB |OR |BU |BU |R |
|-- |-- |V |-- |-- |
|O |X |O |X |X |Auto - High Heat
|O |X |X |X |X |Auto - Low Heat
|<> |<> |~ |X |O |Cool Down / Fluff
|O |X |O |O |O |End of Cycle
|X |O |O |X |X |Timed - High Heat
|X |O |X |X |X |Timed - Low Heat
O = Open (Infinite Resistance)
X = Closed (Continuous)
<> = Either (But not Both)
~ = Doesn't Matter
NA = Not Applicable
TM - Timer Motor (Different Models may use different colors)
WB - Black/White
OR - Orange
BK - Black
BU - Blue
V - Violet/Purple
R - Red
Example: For the Auto - High Heat Dry cycle, the following terminals are continuous:
<TM - OR>
<BK - BU>
<BK - R>
(of course since BK-BU is continuous and BK-R is continuous, then BU-R is also continuous.
This should allow you to test at least some of the cycles your timer switch has
