Yes.
Have the very same caravan, bought new in 2009 and had EXACTLY the same fault. Only additional information was our microwave tripped the Caravan Club circuit breaker as well as the vans before the fuse gave out and the microwave was completely dead.
Changing fuses in the van will not bring it back to life.
I took the van back to the supplying dealers to be told that I must have overloaded things and that they would replace the fuse ( which is apparently a non user service part INSIDE the microwave )as a matter of goodwill but was not covered under warranty and i should consider myself lucky not to to be billed.
When i complained and said that in my opinion i had not overloaded the electrics and firmly believed that the microwave was faulty i was told that i was wrong and that all would be well.
Next time out i used the ( Repaired ) microwave at lunch time with no other electrics on and it promptly gave out a loud flash from the door switch area, tripped the CC circuit breaker and the van circuit breaker and was again completely dead.
Immediately contacted dealers and advised them what had happened and said that this was not going to look good at a Coroners Court if someone is killed due to a faulty elecrical appliance which had already been reported, DOCUMENTED, but disregarded.
An immediate change of attitude was apparent and a new Microwave was ordered and fitted 2 weeks later. The new one has performed faultlessly so far.
