DDE7900NCL Hotpoint Dryer - Overview

first I took the dryer apart 1st thing i did was unplug the power supply (safety first) then I removed the top of the unit then removed the front cleaned all the lint from the inside of the cabinet I found the proper belt size on part select.com the next day I had my dryer belt delivered (which cost 1/3 the price of the local repair shop ... Read more price)
then I placed the belt over the dryer drum and made sure it was in the general location it should be I then replaced the front cover and the top. then I removed the rear cover which was held on by six 5/16 sheet metal screws which gave me access to the drive pulley and belt tensioner the belt goes on by going under the tensioner then around the drive pulley
Then i rotated the drum by hand to make sure everything had clearance I then buttend everything up plugged it and started it up it workd fine and I figure Ill get another 8 years out of it
Thank you partselect.com

first had to troubleshoot... used multimeter to check all switches, they were good.

then checked thermostats, good again.

then checked motor centrifugal switch.. good.

with multimeter i found continuity between heating coil leads and heater housing. coil had broken and welded itself to housing.

... Read more changed coil in short time with restring kit (which got here amazingly fast) and everything is great.

ps: PartsSelect got me the part super fast and it was what i needed. also at a great price. would order from them again.

added note: if i were to do this again i would order the porcelain insulators that insulate the leads to the coils, they were old and very fragile and i experienced some fragmentation.

thanks to PartsSelect
