I have a heat press and it heats up randomly.
Sometimes it's fine.
Sometimes it fails to stop at the temp set.
Other times if it's turned off to lower the temp to below pressing temp, it fails to heat up and sits at a lower temp.
Upon speaking to the supplier they inform me it needs a new 150 quid control board and a new loom and a service.......total cost approx 450 quid plus vat and carriage.
But he let slip it's probably only a 3 quid triac but would not tell me which one.
So I stripped it down and looked for a triac.
I can only see one on possibility on the controller board.
I can see one on the other board labelled triac 2. Which suggests it might not be the only one. But do triacs have heat sinks?
