What are the differences between heater sub-assembly #AP4289905 and heater assembly #AP4038069?
Answer Dick, part number 307178 is the entire assembly which includes the heat sheild and thermal fuse. Part number Y308612 is the housing and element only, it does not include the heat shield and thermal fuse. Thanks!
I replaced the gas coils, thermal fuse and thermostat. The dryer seems to still take a while to get hot. It seems warms at first then at the end of the cycle is hot. Time for drying seems longer than "normal." Any suggestions on what the problem might still be?
With replacing the components that you have already replaced then you will want to look at venting. The venting should be clean and clear. You will want to check from the blower when all the way from the blower wheel to the outside of your home. This is one of the most common reasons for a dryer to stop heating properly.
