Error Messages Continued from Previous Page
E– 4
During a descending ramp the chamber temperature is 50+°F above the previous hold temperature. Condition must persist for 19+
seconds before error is triggered. This error code is disabled when Error Codes are turned off.
Probable cause is Control Relay Failure.
E– 5
During a descending ramp the chamber temperature is 50+°F below the travelling set point. Condition must persist for 19+ seconds before error
is triggered. This error code is disabled when Error Codes are turned off.
Probable causes are Control Relay Failure, Element Failure or Sudden
Drop in Supply Voltage.
E– 6
Negative reading detected at thermocouple (temperature sensor).
Thermocouple circuit installed incorrectly (polarity reversed at some point).
E– 8
During an ascending ramp, chamber temperature is falling. Condition must persist for 22-1/2 minutes before the error is triggered.
Probable
causes are Control Relay Failure, Element Failure or Sudden Drop in Supply Voltage.
E– 9
Improper thermocouple installed or improper thermocouple software setting.
Standard thermocouples for all Evenheat models is TYPE K. The
exception is our line of Crucible Furnaces which use TYPE S.
E– A
Invalid program variable.
E–bd
Excessive Control Board Temperature.
E– d
Chamber temperature 50+°F above travelling set point. This error code is disabled when Error Codes are turned off.
Probable cause is Control
Relay Failure.
E - - -
RampMaster lost power while processing information. Double check program before firing.
ErrP
Brief Power Failure has occurred. ERRP is displayed alternately with firing temperature or hold time. Indicates that power was lost briefly and
restored. The firing program continues to operate. Pressing the Enter key one time during this condition removes the ERRP error code.
PF
Extended Power Failure has occurred. PF is displayed when the controller is powered up after an extended period of non-use (press Enter to
clear and get to Standby). PF is also displayed if power is lost during a firing and the chamber temperature was below 140°F (60°C) or the
chamber temperature dropped more than 250°F during the power failure. In either case, the firing is stopped.
STUc
Indicates that a key on the keypad is stuck in the pressed position.
General Control Failure.
FAIL
Thermocouple (temperature sensor) circuit is faulty.
Thermocouple circuit is broken at some point, usually the thermocouple itself. The
thermocouple circuit consists of the thermocouple, any connecting blocks and the thermocouple lead wire connecting to the RampMaster.

Kiln Trouble Shooting
Listed below are some of the more probable kiln problems you’ll encounter along with their most common cause and repair advice. Please feel free to
contact Evenheat for assistance when dealing with these and other potential kiln problems.
No Display
Check to see that the kiln is actually plugged in. It happens! Also check the circuit protection (breakers or fuses) to see that they are not tripped or open.
Breakers and fuses don’t trip or open for no reason. They indicate a fault which should be investigated by licensed personnel. See below.
Kiln Won’t Reach Temperature
Error Codes associated with a kiln not reaching temperature are E– 1, E– 3, E– 5 and E– 8. A few possibilities here:
A low voltage will certainly slow a kiln down and, if the drop is low enough, it may cause failure to reach temperature. Low voltage is generally associated
with your power service or provider and is rarely a fault in the kiln.
A failed element reduces the heat produced. Failed elements tend to be very visual and are easily seen. With the kiln off (not running and unplugged) have
a look at the elements for any breaks. If you see no breaks in the heating element then suspect a relay problem.
