| Metcal MX-5000 repaired for not heating up |
| (1/1) |
| gregpl:
Didn't see this posted anywhere so thought it might help someone one day. Was using my metcal mx-5000 and turned it off to replace tip then it wouldn't heat up anymore. Everything else would work. When I picked up the iron to use the bar graph did nothing and of course would not heat up. Took it apart and found SMD diode D12 bad. SK16 - https://media.digikey.com/pdf/Data%20Sheets/Diodes%20PDFs/SK12-SK16.pdf Replaced the diode and its working again. Almost bought a new one. Glad I took it apart. |

Thanks gregpl, great job! |

Hi. I have same issue with my MX-5200. Did Q4 MOSFET was heating up that time? Diode D12 was shorted? Thanks |
| gregpl:
I used an IR camera and could see D12 getting hot. It read shorted. Replaced it and its working now. I didn't check any voltages or anything else. Just used the IR to see if anything was getting hot. |

Hi , im new around here ! ehhe :D i was going to check this link https://media.digikey.com/pdf/Data%20Sheets/Diodes%20PDFs/SK12-SK16.pdf EDIT : the link is expired its for the D12 diode , but the link is expired , and I wanted to know what SK12 diode to choose , im getting a used metcal mx-5000 and ordering come stuff from mouser so I told myself , why not get some spare parts , im gonna order thursday so let me know if you have any other spec for this SK12 diode THANKS ALOT ! |
