MasterCycler Pro s

I have a Mastercycler Pro s that will not power up. It has the characteristics of a blown fuse, however there are only two 12 Amp fuses and both seem to be fine.

Is there something else I can look for? Or is there somewhere I can find a service manual to start digging into the unti?

 

Thanks

Hi Jeremy,

The fuses "seem to be" fine - did you check them with an ohmmeter, or just visually? The filament may look intact but could be broken in one of the end caps. I've also seen filaments break clean in the middle and you can't tell unless you hold it up the light. Then you'll see it vibrating.

I'm afraid that's all the help I can give you on Eppendorf PCRs.

Did you ever find out what was wrong?  I'm having the exact same symptoms.  No lights, no fans, and both fuses are good.

Do you hear the power supply relay click after your turn the unit on? Does the Control Panel power up?

No to both questions.

No power supply relay and no control panel illumination points to the power supply board. I am not aware of repair options other than replacing the board.

The power supplies in these units are put under pretty heavy strain by the TE heating/cooling. They're robust, but after a number of years, they will eventually fail. We offer a repair service on them, usually for about half the cost of new power supply, which includes a 1 year warranty. Let me know if you're interested, and I can send you the details.

Best Regards,
Peter

Hi Peter,

I found your website and passed your info along to the equipment owner.  If he's interested, one of us will give you a call and discuss the details.

 

Thanks,

Bryan
