this sears dryer will start if you push the start button down but the second you let off the start button off it stops. homeowner is drying clothes by putting a brick on start button for the complete cycle and it dries fine, motor heating element etc. all work fine. replaced start switch and nothing changed,same result. confused did notice this unit has a littleprinted circuit board about the size of a playing card in the corner of console. dont know if this coul be the problem or not. oh before i forget homeowner said saturday it was really bizarre because it worked fine without neccessity for the brick two out of the five loads they dried . it had never done that before but now its back to brick time again. any help appreciated.
