Relay welded
Measure the contacts:
1. Device at voltage: Blower output must be de-
energised
2. Deactivated voltage: Disconnect blower. There
must be no ohmic connection between blower
output and N.
If one of the two tests fails, replace the unit, since
the contacts are definitely welded and safety can
no longer be guaranteed.
