I service these machines as a indenpendent service provider in the pittsburgh area for all brands of roll laminators including GBC.
the ultimate 65 has a circuit breaker right in the area of the power switch. I have serviced laminators since 1975. I have never found a ultimate 65 that trips that breaker for cause or uses too much current.
ALWAYS replace the wire leads and connectors when replacing any parts in the power circuit.
most probably the leads / connectors were bad and caused both switch failures. they often are brown from overheating and have that toasted look.
so order another new switch, got to home depot and buy some 12 gauge wire and new connectors, those spade terminals.
the heavier wire and heavier connectors help to minimize over heated connectors in the future.
give me a call if you have any questions. telephone tech help is always free.
its sad that GBC dramatically overcharges for parts and service
those orange heat rollers now cost $640 EACH.
