Blown AC - AC Adaptor

Former Community Member

I hope you can help me.

I have a Broil King BBQ which has 3 under lid lights as well as 9 LED lights on the dials.

 Now in the 4 years I have owned this BBQ I have replaced 4 AC -AC Adaptors, all supplied by Broil King.

The adaptors they send all blow from inside out, and I have attached the images.

Some of you have probably seen something like it before and immediately have an idea as to why.

My thoughts are, lack of ventilation and they are packed with a black resin.

 The original Adaptor supplied was 1600mA as were 2 replacements, but the latest one to fail was 1700mA

Unfortunately I do not have a working adapter to enable me to measure the current drawn, but I do remember taking the measurement last year and thought the 1700mA was too low.

Something sticks in my head that the current drawn was 2900mA, but I could be wrong.

    Now the importers for Broil King have sent me another FREE adaptor so that I could measure what is going on. But I can't run the adaptor for too long because we know it is going to fail.

    So with the new adaptor and the three under hood lights disconnected i measured a reading of 0.071 mA, that was with just the 9 small lamps on the dials connected.

    With one 10W lamp connected, plus the 9 small lamps, it measures   1.177 mA, with two 10W lamps, 2.443 mA and with three lamps 3.002 mA

    Now I am not hugely into this type of measuring, I normally work with dBmV, C/N, MER & BER so it is out of my comfort zone and I am an O.A.P. so not in to learning new skills.

    So with the adaptor output being 1600 mA and 20W, is it just solely undersized.

    Should it not be a 3.3 amps (my measured 3 amps + 10%) and a minimum of 40W?
