Life smart infrared heater ls-3eco displays code E4

Good Afternoon friend, I appreciate your inquiry!

Typically on an Electrolux induction cooktop the "E4" error code stands for key sensor for timer. Which means you could be experiencing an issue with the right board, center board, or left board. I would perform a reset on your cooktop and you can do that by flipping the household circuit breaker off for ten minutes.

If that does not assist with clearing any false error codes or the error "E4" continues to display I would suggest seeking assistance from a professional for proper diagnosis and repair. Hopefully this helps. -Matt

Hi, my Dyson AM04 fan heater displaying error E4.

e4 error code comes for defrost. just remove the cover of your split ac, you shell found a sensor there , check for rat cut.

try unplugging it from the wall for 15 seconds and then plug it back in.this normally works for me.if it doesn't work then let me knoe

The above fix is NOT for a Life Smart LC-500-1PC.. this is Life Smart LC-500-1PC. http://lifesmartproducts.com/current-products/infrared-heaters/52-2011-products/332-ls-500-1pc.html

Sounds like the thermostat is out. Order one, and hope it comes with a repair manual!

E0 error - ensure pot or pan is placed correctly
E1 error - the circuit has malfunctioned
E2 error - the temperature sensor is opening circuit or short circuit
E3 error - the voltage is higher (140 - 160V) for 3 seconds
E4 error - the voltage is lower (80 - 100V) for 3 seconds
E5 error - the cooktop surface temperature is too high
E6 error - Internal electronic temperature is higher than normal for 3 seconds
E7 error - Internal electronic temperature sensor is opening circuit or short circuit

The broken water tank flipper will directly cause the unit to not function and the E-4 message will appear on the display screen.

There doesn't seem to be any legit way of fixing this. I tinkered with the pressure sensors and valves, kicked the pressure cooker a few times, still the E4 error presented itself.


I was able to bypass the E4 error by completely bypassing the electronics and wiring the heater coil to get power whenever the pressure cooker is plugged in. It was a very simple job, anyone with any electrical experience can do this.

The only problem is that it is a safety concern as there is no way for the heater to turn off even if pressure is getting to be way too high. There may be a pressure relief valve in the lid but the heater coil won't shut off, so don't leave it unattended! But at least this way to you can still pressure cook.
