***Top dimmer channel 3, Likes to turn itself on to around 30% after a while. i.e. It's level can be raised, but not lowered beyond 30%. The time taken for this fault to appear can be minutes, or hours. It does not seem to be linked to heat - on 18/02/2010 the behaviour was observed when warm, and cold (given a break for 1/2 hour before retrying). This dimmer channel corresponds on the desk to what was "old channel I" - i.e. pre 18/02/2010 it would have been bottom dimmer channel 3.. | |||
***Bottom dimmer channel 3, The transistor/triac looks fried and has continuity between the emitter and collector, also two medium-power 270 Ohm resistors have physically split. This dimmer channel corresponds on the desk to what was "old channel C" - i.e. pre 18/02/2010 it would have been top dimmer channel 3.. | |||
