[Error Code] SHARP MX3070 - F2-49 ERROR

[Leebs14]

Hi all,

I have a MX3070 which keeps throwing a F2=49 error, customer resets it and the machine works for a day or so and then codes again? The book says its a LSU Thermistor Trouble?

Anyone had this before?

Re: SHARP MX3070 - F2-49 ERROR

LSU Thermistors are both inside the LSU.
What is the values for TH1 and TH2 LSU in Sim 44-14 during normal operating conditions and when the code appears?
Reseat the following harnesses: LSU Control PWB - CN6 and CN2, PCU PWB - CN11.
Update the Firmware and ensure there is adequate ventilation on the left side and rear side of the device.

Wow this happened to me just 2 days ago. It was the HUD part of that pwb which is in front of the FFC left side of machine halfway up the rear frame. In 44-14 the temp was correct but the humidity was 99.9%. I replaced that pwb and VIOLA. Fixed!!!
