COLD Mach I

[Arterion]

My 'lil old Mach I seems to have randomly decided to overperform by quite a long way. Now as we all know, machines don't get up one day and decide to do their own thing (unless you're living in a movie), which means there's something wrong.

Basically the display is reading temps of -50 and beyond, and the alarm goes off. I've never had problems like this before, indeed it's been working perfectly for months, just today it's decided to do this. I'm having to run ALOT in the background to warm her up, and even then it only goes up to -43. I thought at first it was an ambient temperature thing, because it's been freezing in here lately but it's baking in here right now and still won't rise above -43. Any possible explanations/solutions guys?

Feel the evap head, is it hot (should be), if not could be the internal heater has burnt out.

could be a rogue boomer has infected ur firmware

/me mustnt watch too much bubblegum crisis

Its a Mach I....no firmware...no heater element. But yes the evap head is cold. The alarm is screaming away as we speak. Any way of resetting the display thing? I think it might be reading temps wrong, as soon as the unit switches on its showing a temp of much lower than it possibly could be at ambient levels.

Could you temp sensor be pooped? Open circuit or summat hence whacko readings?

From what I've read on Xtreme and the such, a leak would also cause crazy temps

Surely that would be higher temps, not lower ones?

For now I don't think there's any danger, just pressing the button to turn the alarm off- if i keep SETI running it stays in the mid minus-forties anyway. I'm guessing there's no harm in it being colder than usual considering people regass mach I's to r507...?!?!

Put a 820Kohm pot between connections 7 & 8 on the controller to allow you to adjust the temperature to keep it reading hotter than -50 deg C.

Now that is one cheeky trick . Could you do it the other way?

By the way, Art, I'll have a lewk in my big box of electronic crap later, and see if I can run one over to you later if I can find an 820k one.
