worcester 24i junior

[rab250]

Does anyone know what pressure the fan on a worcester 24i junior should be producing if i put my monometer on the venturi?

Greater than 3.1mbar negative pressure.

Its not a greenstar thanks anyway.
I think the fan has become lazy and want to check it

Why don't mi's print these figures :mad2: I've always wanted a record of APS diffs but keep forgetting to note them down when I've been servicing!! Ho hum!! Sory rab250 can't help you alas .. does the aps have a minimum pressure setting on it?

Cleaning the Venturi and tubes out works most of the time on these, is it an intermittent lock out fault?

blast the venturies with an air duster
