Hi,

I have had the above machine for about years without any issues. Recently it’s stopped being so unreliable, the thermal overload switch had popped out but that was reset without issues (I presume)

I mostly use it for b&w but last time I used it for c41 about 2 weeks ago it took ages to get the temperature to respond, after twiddling the dials lots it did get to speed as normal.

Yesterday the heat settings would not respond at all, the thermal switch has stayed in. I have opened it up and the fuses all appear fine, though I’ll replace the 800ma fuse for the temperature control panel to see if this helps.

The thermal overload switch does move when pulled and pushed though it’s clearly rusty behind, is it worth putting some contact spray on this to aid it?

Any ideas appreciated!
