Product review (5 stars): Perfect fit to get my Amana gas dryer repaired - recommended
My older Amana natural gas dryer stopped heating the air.  After unplugging the unit, I found the electrical schematic inside the controls head compartment.  Using my Fluke digital multimeter, I tested the fusible links, temperature sensors, wiring, heater/igniter, and the gas valve coils.  I found that the resistance value on one of the coils was significantly higher than the nominal value listed for it in the schematic.  Using the valve part number, I found this replacement coil kit on Amazon.  In reading the reviews, I went ahead and ordered a set.  They were delivered as promised (actually early) the next day (I paid the extra $4 for next day, as I really didn't want to drag all my wet clothes to the laudromat).  I measured the coil resistances on the new coils and they fell within the acceptable ranges indicated on the schematic.  So, I made sure the power was disconnected from the dryer and installed the new coils.  I only needed to remove two small machine screws that hold the coil mounting bracket in place, one-by-one replace the coils, and re-install the bracket.  The whole job took 15 minutes, and now my dryer's heating the air perfectly.
