We are so confident in our work that we provide a 6 month warranty on each repair.

We have a 60 unit Boumatic rotary parlour built in 1998. Over the years we have incurred various electronic failures, mainly due to moisture and power surges/failures. Over the last six years Weichert Electronics have been able to assist us with;
  • repairs to 4600 detatcher boards, repair burnt out tracks, replace failed milk flow potentiometers, installing superior on/off switches etc,
  • repairing failed pulsation boards and adding fuse protection on repaired units
  • replacing burnt out relays on guardian wash unit
As well Roger is able to reprogram our detatcher boards so that when they are returned to us we know that they are all ready to work!

We have also utilized Weichert Electronics to repair electronic boards on electric fence units, centre pivots and our oven!

You will not be disappointed, they fix things quickly and efficiently.
