Red Chilli d Flash issue

[ericheartsu]

so of course around 6pm as we are doing our final job for the night, our red chilli flash starts having an issue. I called M&R tech support, but i have to call again in the morning, as we didn't really get to the root of the issue.

Our flash is hitting it's set temp, way to fast. in our current testing, It's hitting 300 degrees in about 3 seconds. When it hits the temp, it's shutting the bulbs off. Even with low power, and my time set to 10 seconds, still hitting my set temp in about 3 seconds and shutting off.

There is no possible way i'm getting to temps that fast. I just went out to the press, and did a dry run, no shirts, and the press has been sitting for about 3 hours. With my temp gun, i'm getting a reading of about 150ish degrees on the plattens, and the temp read out on the flash is hitting around 300.

What could be going wrong?

Sensor itself likely getting direct heat as opposed to reading it from substrate.
Is there a way to bypass the sensor for the time being and make it operate on time
like a regular flash?

I'm up waaaay to late and beyond tired right now but are you running flash unit from control panel on the auto or running it on the flash itself?

Take a q-tip and denatured alcohol and gently clean the lens of the sensor. Make sure there is no lint blocking the air flow to the sensor inside the top cover and or the blower is running.

thanks rich, i'll try that now!

Oh yeah, that sensor moves. It might have come loose or someone might have made an adjustment and forgot they did

We had one of the earlier flash units and the sensor itself had to be replaced.

The temporary fix we did was to rewire to bypass the 2000F overheat(or similar) which was stopping it from working properly.

Our issue may have been different than yours but it sounded somewhat familiar...but it was at a time reaching the cutoff way before it should have.

i believe it's a sensor failure. I thought i'd replace it today, but looks like M&R parts only sent the bracket not the sensor...so we gotta wait another day to make sure!
