radio interference

Member - Tanka (NSW) replied:

I would make sure your fridge is earthed well with a cable as thick as the power wire, to something connected to the chassis, or the chassis itself. If that does not help you could try fitting a suppressor to the radio, you could get one of these from your local auto sparky at a reasonable cost, or from somewhere like Jaycar.

Probably should provide more information - how its wired e.g. direct to battery, or via a cig lighter plug, also and type and model no of fridge.

1 reason for this is that some early model Waeco's had a recall fix for that issue.

If its not that then begin finding out source of problem - which radio band does it interfere on, and then , can you hear interference when aerial is disconnected etc

Notso perfik,

Waeco fridges have a long history of creating interference on the AM and HF bands. This was looked into some years back by valued member Footloose (sadly now passed on) who proposed and discussed a fix in thread 31254. The problem was also discussed on the Yahoo Codan group where Footloose was also active. From that group (probably from Footy himself) comes this diagram for a filter which was introduced into the power lead, preferably close to the Waeco's electronics assembly. (The Waeco uses a 24V compressor and the interference comes from the 12V to 24V conversion.)

Power Supply filter for Waeco fridges

Similar filters are available from electronic supply places, but look for one suitable for say 10 amps, not low current mains filters.
