What cld cause sharp 5316 indicating an open thermistor

Google search reports thermistor error. One of several possible fixes described: https://www.thecopiernetwork.com/sharp-black-and-white/sharp-ar-5316-code-h2-20301/

Thermistor open detected. Thermistor defect
MCU PWB defect
Fusing section connector contact
failure
Power supply failure
Fusing unit not installed
on
Check the harness and the
connector of the thermistor and
the MCU.
Clear the self diag display with
SIM 14.

H2- 01_ thermistor open

Hi,
H2 : mean thermistor is defective.
to resolve this problem you have to choice if the first one didn't work go to the next one

• do the following procedure to reset the error :-

press "R" key __ "Interrupt" key __ "C" key __ "Interrupt" key __ "14" __ " ready" key

• If the first procedure didn't solve your problem contact your customer service center to replace fusing thermistor.

thank you for using fixya

H2 signal is thermistor open
check the harness and the connector between the thermistor and the PWB use TC 14 to clear the self diagnostic display.

It appears there is a paper jammed in the thermistor area, remove that piece and check thermistor. Clean it or check its connection for open circuit and rectify.

H2 means the thermistor is open or defective.

Try to press the copy button when h2 appears you'll see the sub 00. You dont need to replace the whole fuser unit. Try first to cancel the trouble by entering the simulation.

Try to press the # - interrupt- C- interrupt (one after the other.) then enter 14 then copy button. If it doesnt work replace the thermistor.

The last part that you'll replace is the main board but that rare. Mostly the thermistor is defective when that trouble appears. Hope it could help you a lot.

An error code of H2 om a sharp 5316 indicates an open thermistor.A thermistor is a small electronic device that regulates temperature.You will need to call a copier technician.An Ar5316 operates at 16 copies per minute.Good Luck!

An H2 is an indicator that the temperature sensing device is reading open, preventing the machine to warm up. There is only one way to correct this and that is to replace the thermistor, and that takes a technician. Not a hard job but a novice could get into trouble and make matters worse.

there might be some dirt on thermistor above the heater upper roller pls check and clean the fuser unit then use simulation 14 to reset the machine enter simulation by presssing #,interrupt,c,interrupt in sequence display is then off, then no. 14 then start key h2 disappears ok
