I recently purchased a used coin operated Maytag gas dryer model MDG12CSAAW. Everything has been working great until the last couple of weeks when I noticed that the dryer was being used, but there was no money in the coin box. When I took off the access panel, I found that the plastic piece that fits on the end of the timer rod had come off allowing the timer to run continuously. I manually rotated the cam timer to the stop position and put the plastic part back on the rod. I then verified that the timer stopped after being restarted. Now the dryer runs, but does not heat? Did I incorrectly position the cam when I manually rotated it? Does anyone know the correct stop position? The timer says to see the owners manual for adjusting the timer, but I do not have one. ANy help would be greatly appreciated.
