    I have changed a few Lae digital readout controllers where the general set up is the controller has a live and neutral to power the actual controller, then there is a live connection and a switch live also the controller has a probe to monitor the fridge and turn it on and off accordingly to the actual set up. Last week I found a controller where there is a resister between the live the switch live and I don’t know why there is, any help ?

    Is it definately just a resistor ? Could be perhaps be a voltage spike suppressor to protect the contacts of the switch. Either a semiconductor device or a capacitor and resistor connected in series.

    What model LAE controller is it?
    The fridge ones I have used never had resistors.
    Looking at the LAE site, none of them use a resistor like suggested, was this as supplied or fitted by someone who fitted the timer?

    Actually, is that a switched live or just a relay output contact?
    The resistor may be just link.
