Charles, Have you dismantled the duct work on the heater assembly, and checked for any clogs , debris or lint built up in the duct work ? " diassemble the cabinet cover and condensing bellows. Is there any foreign object in condensing bellows. Disassemble the dry fan assy and dryer duct upper, and clean foreign object in duct and fan." Heres some resistance checks to make : After the power is off, is the resistance of
dry heater element 10 ~ 40Ω? Is the heater thermostat "closed" at room temperature ? Is the resistance of the two(2) thermistors on the condensing duct and dry duct 2.5kΩ ~ 180kΩ (at room temp. 75 to 80 dgrs.F.) If all checks are proper, you'll need a new control board.

Heres some meter usage information if you should need it,:

Good Luck and Thanks,

[FONT='Times New Roman','serif']OK, it seems lint was trapped in the fan causing it not to spin and lock out the machine. So what I did was took the 4 screws (Phillips) off the back removing the lid, took apart the fan housing 4-6 screws (Phillips) tried to turn the shaft and it was stuff by some lint, so I cleaned and put everything back in reverse and now it works. So hope this helps anybody have the same problem.[/FONT][FONT='Times New Roman','serif'][/FONT]

Joe - I too am getting this DHE error (WM3677HW machine) I tested the element which registered 11.5 and checked continuity in thermostat. But when checking the three thermistors (two on rear duct and one at the front boot) I got no reading at all. Does this mean I need to change all three?
