TROUBLE SHOOTING – SERVICE TIPS
Problem Possible Cause Suggested Remedy
System or Boiler Overfilling or Flooding
(Steam Boilers)
New boiler water content smaller than old boiler
Install Boiler Feed System with Receiver Tank
Large enough for Condensate
Boiler water feed rate or pump rate too fast
causing water level to collapse (due to collapse of
steam bubbles in boiler water)
Reduce Feed Rate
Foaming, priming or surging due to poor
water quality
Clean the Boiler
Excessive Water Level Bounce
(Steam Boilers)
Poor water quality, causing foaming and surging Clean the Boiler
Incorrect near-boiler piping, such as undersized
or incorrectly placed risers
Pipe per Manual
Boiler water feed rate or pump rate too fast Reduce Feed Rate
Rapid Cycling
(Steam Boilers)
Air vents or traps not venting air, preventing
steam from getting to radiation and pressurizing
the air pocket
Replace Vents or Traps
Pressure differential on pressure control too close Adjust Control Differential
Nuisance outages of water level control due to
boiler water level bounce
See Excessive Water Level Bounce Above

Table 10.2: Capable Controls Series 5 Ignition Module – Sequence of Operation and Error Codes
Trial for Ignition – 90 seconds, 5 minute wait between trials for ignition.
LED Indications, Normal Operation
Green, blinking rapidly Trial for ignition
Green, on solid Flame detected, pilot/main burners on
Green, 1/2 sec on, 1/2 sec off Wait time between trials for ignition
LED Indications, Error Operation
Upon detection of a fault by the ignition module’s internal diagnostics, sparking is turned off and pilot and/or main gas valve(s) are closed.
See LED error codes below. To reset module and clear error, interrupt call for heat (power).
Red Flashes Error Definition Suggested Remedy
1 flash N/A (non-retry models only) Not applicable
2 flashes Flame sense stuck on If pilot lit with all power off, replace gas valve. Otherwise, replace module.
3 flashes Pilot/Main relay failure Replace module
4 flashes Repetitive flame loss error Check gas pressure, flame size, electrode position.
5 flashes N/A (models with flame rollout) Not applicable
6 flashes N/A (models with APS sensor) Not applicable
7 flashes Internal control error Replace module
Solid Red Line Voltage/Freq Error Verify voltage and frequency of incoming power.
