Dryer Electronic Controls

At first glance dryer electronic controls seem very complicated. However, an electronic control on a dryer is simply a replacement for the traditional timer.

Electronic controls use low voltage within with a printed circuit board to switch relays on and off to control all the loads in the dryer.

A load on a dryer is something that does work. A heater heats, the motor turns and the end of the cycle buzzer makes noise. These are all loads and must have wires that run all the way back to the contacts on the relays.

Relays can be on the board (electronic control) or in a relay pack usually located near the control board in the control panel area.
