This problem is a bit of a long time ago, but for anybody else with a similar fault. If you have replaced the correct size fuse, it could be that fan heater is running rough and taking too much current. When thee motor runs does it sound laboured and with noisy bearings? My fan motor is clearly running with friction in the bearings and I measured the current to be more than 30A which certainly seems like a lot.
