TABLE 13.0 - ERROR CODES
Error
Code Meaning Possible Cause
4 Low Flame Signal
• Low gas pressure at gas valve inlet
• Partially plugged pilot tubing or pilot orifice
• Loose connection in ignition cable or ground wiring
• Dirty pilot electrode/ground strap
• Pilot electrode porcelain cracked
• Damaged pilot hood/ assembly
• Defective control
6
Pilot Flame detected when no
flame should be present
• Defective gas valve
• High gas pressure
• Defective control
18
Internal electronics failure
• Possible internal problem with boiler control. Cycle power to the boiler and replace
control if problem persists.
23
Flame sensed during 1.7s pre-
purge (before pilot valve opened)
• Defective gas valve
• High gas pressure
• Defective control
32
Boiler water temperature sensor
failure
• Loose sensor connection at control
• Defective Sensor
• Defective control
35
Duplicate Zone
Error code reserved for future use
55 Damper failed to open after 60s
• Loose or defective damper harness
• Obstruction in path of damper blade
• Defective damper
• Defective control
56
Power at end of limit string when
it shouldn’t be.
• Control, vent damper, or damper harness is defective. With Error 56 present, and
no call for heat, unplug damper harness from control and check for 24VAC between
termminal P6-5 on control (see Figure 9.2 for location) and ground. If voltage is
present, replace control. If not, inspect the damper harness for shorts or miswired con-
nections. If no harness defect is found, replace vent damper.
57 Grounded pilot electrode
• Condensate or foreign material is shorting pilot electrode to ground.
• Ignition cable insulation is damaged and touching ground.
• Pilot is damaged
58 AC Power Frequency Error
• 120VAC power supply frequency is incorrect (Should be 60Hz)
• 120VAC power supply is dirty (consult electrician and/or Utility)
• Boiler water temperature sensor common (center wire) is damaged and shorted to
ground
59
Line voltage error
(Supply voltage too high or low)
• Power supply voltage is incorrect (should be 120VAC nominal)
• Defective or incorrect 24VAC transformer
• Loose 120VAC connection or 24VAC connection between transformer and control
60
Thermostat input higher than
threshold
• External voltage is applied to thermostat connections (most common cause is external
transformer in old thermostat wiring.
61 Line Voltage Unstable
• 120VAC power supply is dirty (consult electrician and/or Utility)
• Loose 120VAC connection or 24VAC connection between transformer and control
• Large electrical loads elsewhere on the installation are switching on and off, causing
incoming voltage to swing excessively at boiler.
63 Maximum recycles exceeded
• See Error Code 4 above (boiler lost proof of pilot 6 times in a row)
64
Internal failure
• Loose or defective damper harness
• Obstruction in path of damper blade
• Defective damper
• Improper pilot operation
• If problem persists, replace control
89 EnviraCom communication lost
Communication lost between boiler control and certain Crown control options. Consult
Crown control option manual.
