Try this: http://www.manualslib.com/

I Googled this: Fuji air conditioner E3 Error
One item seems to have the answer:
http://errorcodeairconditioning.blogspot.com/2010/10/fujitsu-air-conditioner-error-codes.html
"E3:00 Return air thermistor short circuit"
So more than likely you have a crossed wire issue. good luck.

E3 error on LIfesmart heater


Even after replacing thermostat and motherboard offered from company, my heater would trigger e3 error code and shut off. After several (maybe 100!) different attempts to plug in and operate, here is what worked for me!
Depress the power button on the heater while plugging in to wall circuit. Continuously depress power button. It will run through a test cycle and attempt to start. Keep depressing the power button as the heater tries to start, then shuts down with e3 error. While the power button is still depressed, unplug the unit from the wall. When I plug back in the wall the E3 error is gone. Good luck

Ac unit turns off after about 2 mins and has error code "E3" on panel. Unit is a Quietmaster Electronic series SM21


Hello
E3 is usally a inside fan error code.Possible the fan is going bad or the unit is not wired as it should be.
Check that your incoming voltage is what the unit calls for and thhat all wiring to the unit is correct.

E2 error code in samsung split AC


From all Samsung recomendations... if your air conditioner displays E1 in the display panel and won't turn on, it means that the Room Thermistor (a device connected to the thermostat that detects room temperature) is shorted or defective, and you need to have your air conditioner serviced.

If it displays E2, E3, or any other E error, you also need to have your air conditioner serviced.

To arrange for service, contact Samsung Customer Care at 1-800-Samsung (1-800-726-7864) any day between 9:00 a.m. and 9:00 p.m. Have the model number and serial number of your air conditioner on hand when you call.

Hope helps.
