My timer has become not accurate. For example the for normal laod the timer states 48minutes, but the cycle only runs 24minutes. It is the same for all the different types of cycles. ie. light load through bulky.
Which part controls the cycle time.
Answer Von Stegall,
You will want to test the exhaust thermistor as it will play a role in the length of time that the unit runs for. At room temperature the resistance of the thermistor should be between 11.5K and 13.5K ohms. If not within this range then replace the thermistor and if it checks ok then replace the control board.
