Re: Admiral GC2224GEKW damper
Hi.
The heater kit is required when in a humid environment. Moisture settles on the damper door and condenses then freezes, This usually hapens early on in the life of the appliance unless something has changed i.e resited, double glazing or a range cooker fitted etc. Anything to change the immediate humidity.
If you are replacing the damper a heater kit wont go a miss but check also that the door hasnt dropped like the last one I attended. It had a few dampers fitted by the original engineer, but they missed the door had droped allowing warm air to enter. Caused the same problem though.
