We have an LPG ideal boiler branded for MORCO under warranty. It’s fitted to our static caravan which we have just returned to after absence of 4 months. On return we found the pcb has failed with a burnt component. MORCO have refused the warranty stating it is a power surge of 317v ac and therefore not covered by their warranty. Western Power have no record of a power surge during the period in question.
Q1. From the photo below how can they categorically state that a power surge is the cause?
Q2. Why couldn’t it be a simple component failure due to say faulty soldering. Do these components never fail in a boiler?
Q3 The fuse has blown in the boiler rated 4a. The fuse in the main plug 3a has not blown and the consumer unit has not tripped. If a power surge, wouldn't it trip the consumer unit as well?
Any experts out there who can help please
