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?

You need to use the right voltage heater to prevent that and the right
wattage to prevent melting the fridge.
