Controllers

Ok – possibly the single most common issue I hit each year is this problem.

First up – there is no fuse and no battery in the controller! Silly I know – to have a ‘fuse’ message and a battery symbol at the same time.

The average DIY would look for a dodgy fuse or a faulty battery.

What the message actually means is that there is either a fault in the controller or a fault in a solenoid.

The way to determine the issue is simply to remove wires and keep resetting the controller and testing it. If it operates perfect with one of the wires out then it’s more than likely a solenoid coil sending a ‘fault’ message.

However if the controller display is flickering or if the fuse message only appears intermittently then chances are very high that the box itself is at fault and will need replacing.
