hi there,

my fridge is icing up and when i looked inside i found its 23" defrost
glass tube heater shattered. it had a sticker stating 400w

i found a 12" replacement of around 30ohms for a few bucks which i
fitted. it iced up again and checking the heater i found it fused. part
of the element coil broke from excessive current.

what could be the problem? defrost thermostat? timer? resistence in
replacement heater too high? how can i calculate it properly? does
length of replacement heater make any difference to why it blew?

thanks
