5.3.2 Timer
Operation
The timer runs in 2 ways, Automatic and Timed Dry.
In automatic, the timer only advances when the PCB powers the timer motor.
Power is supplied into the TB connection on the timer. Power for the motor is fed first from the TC
terminal on normal operation and from the TH terminal on Extra Care. If on Extra Care, power is
fed from TH on the timer, into terminal 2 on the selector, out of terminal 4 and back to TC on the
timer.
From the timer, power is switched through the hi-limit thermostat and to the start switch, which is
selector terminals 14 to 13.
Power is then supplied from the start switch, which powers back from the motor feed, then goes
through the timer motor to the T terminal on the timer. The neutral for the timer motor then feeds
to the white wire to the PCB.
From the PCB, neutral is fed back to the S terminal on the timer then back to the mains terminal
block.
The PCB measures moisture across the sensing bars on the front duct assembly. As the clothes
slide past the bars, the PCB reads for a current across the bars. When the clothes are dry the
current ceases so the PCB advances the timer.
