    HBN131550b/02. This oven will not function. All that happens is cooling fan comes on straight away when oven is switched on. Timer can be set ok. Limiter stat under back of selector 421793 is o/c. Other stat rear lhs is c/c.Replaced limiter stat. Is there such a thing as a wiring diagram for these ovens. Could do with details of connections on back of timer and selector. Its looking like timer but would like to be 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d}.Paul

    Is it a special clock of some kind? Most clocks have a maximum of 6 connections. 2 for the supply and 2 each on the two relays. It doesn’t sound like a clock problem to me if the fan is coming on. Have you bridged the relays out? Steve.

    Probably the main oven selector switch. Have had 2 recently with these symptons and both were cured with a new selector switch.

    Thank you both for your helpful advice. My gut feeling is the selector switch even though it is absolutely spotless. Upon testing across the first set of contacts(l and r) on selector there is no circuit formed on any function selection.
