Error Message:
FAIL

Description: Steady display all thermocouples (T/C’s) have failed. If flashing thermocouples of a zone control kiln has failed.
Causes: An open thermocouple circuit is caused by a broken thermocouple, damaged wire or bad connection. In rare cases the computer board can be bad. 
Correction: Change Thermocouple, check wiring connections and as a last result change the touchpad (unlikely issue).
Possible Parts:
Skutt Type K Thermocouple Replacement – Element Only – 8 Gauge
Type K Thermocouple – 8 Gauge – 6” Long
Skutt Type K Thermocouple (8 Gauge) with Block and Wire

Error Message: E-0
Description: Software error.
Causes: Caused by hardware or electrical noise, can be caused by electrical spikes, surges, or arcing.
CorrectionRecheck the selected program, and reprogram if necessary.
Possible Parts:
Skutt Touchpad with Circuit Board (For Standard Type K Thermocouple)
Skutt LT Touchpad with Circuit Board (For FireBox and GlazeTech kilns)

 

Error Message: E-1
Description: The temperature is increasing less than 12 degrees per hour during a ramp segment, where the temperature is programmed to increase. This slow rate must persist for 22.5 minutes before the error is displayed.
Causes:Worn or old heating elements. Low voltage to the kiln. A broken heating element or faulty relay. Burned or broken wires to the elements or relays. Electrical noise.
Correction: Check elements. Check Relays. Use VOLT Menu feature to check voltage if available.

ossible Parts:
Elements
Skutt Relay – 25 Amp (Black Case)
Skutt Relay – 25 Amp (Clear Case)
Skutt Relay – 50 Amp – Single Phase for KM-1 Wall Mount
Skutt Relay – 40 Amp – Three Phase for KM-1 Wall Mount

 

Error Message: E-2
Description: During a hold segment the temperature rises to greater than 50 degrees above the hold temperature which was set. The temperature must stay 50 degrees above this set temperature for 18 seconds before the error is displayed.
Causes: Stuck relay.
Correction: If only one section (or relay) remains on then it is a stuck relay. Turn of breaker to shutoff power to the kiln.

Error Message: E-3
Description: During a hold segment the temperature is more than 50 degrees below the hold temperature which was set. The temperature must stay 50 degrees below this set temperature for 18 seconds before the error is displayed.
Causes: Opening the door or lid of the kiln. Relay or element failed during firing.
Correction: Check relay. Check elements.
Possible Parts:
Elements
Skutt Relay – 25 Amp (Black Case)
Skutt Relay – 25 Amp (Clear Case)
Skutt Relay – 50 Amp – Single Phase for KM-1 Wall Mount

Error Message: E-4
Description: The firing is in a ramp segment where the temperature is programmed to decrease and temperature is more than 50 degrees above the previous hold temperature. The temperature must remain 50 degrees about the hold temperature for 18 seconds before the error is displayed. E- 4 is the same as E- 2 except that E- 4 occurs during a ramp phase rather than a HOLD.
Causes: Stuck relay. Skipped step feature.
Correction: Check relay. If E- 4 occurs when skipping a ramp phase, press a key to clear the error. Allow the kiln to cool to within 50 degrees of the next hold temperature. Restart kiln and skip steps until you get to the segment you want.

Skutt Relay – 25 Amp (Clear Case)
Skutt Relay – 50 Amp – Single Phase for KM-1 Wall Mount
Skutt Relay – 40 Amp – Three Phase for KM-1 Wall Mount

 

Error Message: E-5
Description: A Negative temperature is displayed. If this occurs almost immediately after starting a firing it generally indicates the thermocouple is connected incorrectly. To correct this situation, ensure the red and yellow wires are connected correctly to the controller and at all junctions. You can identify the red lead on an unmarked thermocouple with a magnet because a magnet will be attracted to the red lead. If this error is displayed during the course of a firing it generally indicates a problem with a relay or element. 
Causes: Open door or lid. Bad elements. Bad relay.
Correction: Check thermocouple wiring. Check elements. Check relay.
Possible Parts:
Type K Thermocouple Block
Type K Thermocouple Wire
Elements
Skutt Relay – 25 Amp (Black Case)
Skutt Relay – 25 Amp (Clear Case)

Skutt Relay – 40 Amp – Three Phase for KM-1 Wall Mount

 

Error Message: E-6
Description: A Negative temperature is displayed. If this occurs almost immediately after starting a firing it generally indicates the thermocouple is connected incorrectly. To correct this situation, ensure the red and yellow wires are connected correctly to the controller and at all junctions. You can identify the red lead on an unmarked thermocouple with a magnet because a magnet will be attracted to the red lead. If this error is displayed during the course of a firing it generally indicates a problem with a relay or element. 
Causes: Using the kiln in temperatures below 0 degrees °F (17 degrees °C). Thermocouple (T/C) connected backwards, red and yellow leads reversed. Board has been damaged by static electricity or ESD (electro static discharge).
Correction: Check T/C to make sure it is connected properly. Do T/C bypass test, if temperature reading is still negative, the board has been damaged and needs service.
