Here is the parts breakdown
Replacement parts for AMANA AEM697W | AppliancePartsPros.com

I went through the parts and could not find a moisture sensor so odds are high that you do not have one.

I assume timed dry runs OK?

You may want to open up the control console to see if they have put the wiring diagram in there or it may be glued on the back. I cannot find a diagram on the net. I think the unit is made by Whirlpool.

Here is a good link with basic info

Your unit may be close to the following without a belt switch but you really need to find a wiring diagram.

Check out #34 Sample wiring diagrams
#6 Old style Whirlpool
Check the operating thermostat on the blower housing to see if it has 3 wires going to it.
If yes it could be that the Normally Open contacts are not closing.
The Normally Closed contacts would be used to power the heater.

Hopefully the above will help a little.
