Heater malfunction ?

[Gamer]

system boots fine, temp in bios is -33°, temp on disp = +5° - +10°.
fans stay at high speed.
got no condensation before, but now there is alot.

what are my options, what is broken ?

[bowman1964]

where is the condesation forming at.under the hose and down the side on the cooling head maybe?

[Gamer]

on the microfreezer.

started the unit again and now I got an ERR 4, this means an overheat error ???
disp temp is now 55°.

strange, because the unit works.

[Gamer]

got it back online, only tempdisp is 36°, biostemp is -33°
so my unit is not faulty.

ok, this has to be the heater ?

can I disconnect it and still use the prom or not ?

[bowman1964]

Yes there are 2 red wires comming out of the insulation near the compressor.if you dont see the plug they connect to or you just want to disable the cooling head heater cut one of the 2 red wires.it will kill the heaters,and it will run fine.the black wire is the thermistor wires.

[Gamer]

thx,
did locate the wires.

doesn't it go to full error when I switch it off ?

[bowman1964]

Not on any of the ones i have done.
i have cut 3 trying to see if i could get colder temps.but one was a mach II and i cannt see if it gave it a error,because i only have the bottom hardwear.
but they worked fine.

[Gamer]

and howcome the displaytemp is so high ?
maybe the sensor is faulty to.

[bowman1964]

Well hard to say.if the heater got hot enough once it could have caused a short in the thermistor wire.but without checking it with a meter it would hard to say.
so it is reading that high?

[Gamer]

even had in into the 60's :p

cpu is not broken, it works just fine.

strange thing I got here.

[Gamer]

this is strange ???

I didn't touch the system and it works again ?

was going to take the prom out of my case, and tried it for the last time.
disptemps was 22° and went fast to 0°.
me :confused:

let it go to -33 and it booted like nothing ever happend.

now, I've been around alot, but this I don't understand.

I didn't touch anything, not even opend the prom or whatever....

this is :eek: and :banana:

explain this to me please, cause I'm :shrug:

did you cut the red wire?

i am not there,but if the heater was shorted it is possable it may pull the controll too hard and maybe causing the display read errors.
we are only guessing,would be nice if it stayed working.;)

[Gamer]

i didn't cut anything, or do nothing.
because it's still in warranty.

working for 2 hours now without a hikup.

[bowman1964]

Just keep those fingers crossed:cool:

[Gamer]

lets hope so.

thx for the help M8.

I've had this exact problem, at first I had problems like you, it would sometimes read a little high but restarting the unit could get it to read normal as time passed my unit would read more extreme temps to the point where it would read 60°C after 8 hours off and would no longer read normal no matter how many restarts I did. Of course with it reading above 40°C it would beep and shutdown. In the end I rma'd the unit, which took forever (4+ months from my first email about the problem).

I hope your unit is just having a hickup.

[Gamer]

it's running just fine now, tried several times with cold boot.

Does the heater stay on whenever the Prommie's plugged in, or only when the Prommie is cooling?

Did they tell you what problem(s) they found? That information might be very helpful to others.

No they never did say what the problem was, I assumed the thermistor had gone bad. Chip-con has a communications problem, they frequently took 5+ days to respond to an email and then they usually had to contact their supplier for anwsers (which required even more time).

[Gamer]

omg, luckely my setup started this morning without problems.

indeed, Chip-con service is not what it used to be anymore.
to bad.

[Gamer]

ok, the problem is not gone.

same §§§§ today :(
RMA I guess.

it look like the sensor is faulty, not the heater.

is it possible to replace the sensor by someone else then Chip-con ?

[Gary Lloyd]

Maybe chipcon would be willing to ship you a new sensor.

its integrated into the cooling head, I dont think replacing it is an option :(

First Mk1 I've heard of with a broken sensor

My mach I had a broken sensor, I had to RMA it.

[Gamer]

damn, let hope this doesn't effect the cooling of the unit.

it worked so good....

[bmg]

Does the heater in the cooling head stay on all the time the Prommie is plugged in, or just when the Prommie is actually cooling?

[JCviggen]

the heating element is not the problem here... the sensor is. because its constantly reading too high, the heating element will not turn on (only at -33C when the fan speed drops)...

Gamer, I'm not sure they can just "fix" this... i think you could get a replacement unit instead

Since the Mach II cooling head heater apparently gets extremely hot, I was wondering if that could be related to the temp sensor failures, which seem to be happening more frequently in the Mach II versus Mach I. The temp sensor reading extremely high would indicate either a short circuit or open connection, depending on whether the temperature sensor had a positive or negative temperature coefficient. Someone with a malfunctioning sensor could measure the resistance with a meter. When my Mach II arrives in a day or two I may try to reduce the heater temperature a bit.

[Gamer]

dont want a replacement unit, want my old one back :p

it gives me verry good temps, so you know why I want the same unit back.
I ship it today, let's hope it doesn't take months to get it back.

the heater start when temps are 5°, because else you would get already condensation before it reaches -33°.

[JCviggen]

I think its unlikely you can get the same one back m8... even if you could, it would probably have to be recharged and have different temps

the sensor is integrated in the cooling head and cannot be removed...so you see the problem with that

the heater on my proms never started before -33. Plastic and insulation dont get ice cold (condensation) in a few minutes m8

[bowman1964]

there is one other option.you may or maynot like it.but i can tell you it will fix it.

if the sensor is off ,which it sounds like.

just connect the heaters up directly to a volatge source.this can be done easy,and wont leave any signs you did it if you are carefull....the heaters will work all the time or by a on/off switch.but i would leave them on.

by unpluging the connection at the board and repluging it to a power source you do not cut or damage anything,so no signs of damage to void a warranty.

[Gamer]

unit was shipped today to Denmark for € 60 ($).
now lets hope it doesn't taken them 3 months to repair it.
