I had problem with p1 not heating up so

I replaced the heater for new one

My temperature setting for p1 solution is 42 degrees

But now its overheating above the required temp and goes up to 50+

I even swap out the thermostat

I cannot print even if I change the P1 settings to 50 degrees

Keep getting error

Any ideas why?

In my Noritsu case, mostly likely your new P1 heater could be wattage too high so current damaged the P1-control solid state relay, either half wave or full wave short circuit,,,, thus new P1 heater is always "ON"  even though the tank is not calling for heat . . . .  my wide guess

Before change new heater

the original heater blown the fuse so the connection wasn't working

I got someone replaced with new fuse then change with new heater

i also tried using ps heater with less wattages but still overheating to 43 degrees

So the P1 control SSR is currently damaged you say and needs replacing??

Does anyone have photo of what the SSR look like?

Ok

I have located it but how to replace?

Can it be easily pulled out individually or is more complicated then that?

Is it just the bottom bit or the entire thing?

I'm not qualified for this but just to clarify what needs to be done

and where can I get replacement part if possible

Thanks

The SSR will need to be de-soldered from the circuit board to replace it.

The part number of the board is showing as J391466, search for that in google and see what you find.
