Hello. I have an old but good GE electric dryer mod. # dbxr453et. It runs and cycles through times but does not get 'hot'. It will get warm only. I've read through several threads and have learned that it could be more, or simpler, than just the heating element or coils. So I thought I'd post to get specific instructions on how to go about determining what part I need to replace and what parameters I'm looking for on my model in testing w/ohm meter.
