Bed suddenly stoped heating. Hi, i was ready to print, everything was ok but when "Bed heating" it didnt heat up, the led in ramps does not light up... thermistor seems ok.... now im testing in proterface and the led does not light up. I got some temperature errors in the past when not totally cooled down and i ordered to reheat, only 2 times... (just in case it matters) thanks for your help! ;) https://reprap.org/forum/read.php?4,618612,618612#msg-618612 Sat, 14 Mar 2026 18:49:44 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?4,618612,621435#msg-621435 Re: Bed suddenly stoped heating. https://reprap.org/forum/read.php?4,618612,621435#msg-621435 Dust Reprappers Thu, 04 Feb 2016 15:26:51 -0500 https://reprap.org/forum/read.php?4,618612,621422#msg-621422 Re: Bed suddenly stoped heating. https://reprap.org/forum/read.php?4,618612,621422#msg-621422 Donziboy2 Reprappers Thu, 04 Feb 2016 15:06:49 -0500 https://reprap.org/forum/read.php?4,618612,621351#msg-621351 Re: Bed suddenly stoped heating. https://reprap.org/forum/read.php?4,618612,621351#msg-621351

It came back, i checked my wires and it was all ok, now its gone again... thermistor reads ok, but this will not heat up (red led will not turn on)

12v are reaching, hotend and fan work ok... no idea what is happening... :/

Is there 12v at the heated bed connections?
Check the pins inside the connector housings, are they tight?]]> orictosh Reprappers Sun, 31 Jan 2016 12:50:03 -0500 https://reprap.org/forum/read.php?4,618612,618798#msg-618798 Re: Bed suddenly stoped heating. https://reprap.org/forum/read.php?4,618612,618798#msg-618798

Check Do you have 12V at the bed connections when you request to turn on the heat bed in proterface?]]> orictosh Reprappers Sun, 31 Jan 2016 08:30:34 -0500 https://reprap.org/forum/read.php?4,618612,618612#msg-618612 Bed suddenly stoped heating. https://reprap.org/forum/read.php?4,618612,618612#msg-618612
