[Error Code] H4-03

[JohnoLFC]

Afternoon,

Does anyone know what a H4-03 error code is on a Sharp device?

I've had a quick search on here and Google and cant find anything,

Cheers

Re: H4-03

More information would be helpfull. Generally on Sharp machines a H4 code are telling you that the fuser did not get to temperature in the appropriate time allowed. The 03 guides you to which thermistor is not getting to the correct temperature.
Maybe broken lamp. Maybe a open thermostat. Maybe a defective pcu pwb.

Buy a service manual, it will tell you everything you need to know.
