IGNITION CABLE....    

a.

 

Make sure that the ignition cable does not touch any metal surface. 

b.

 

Make sure that connections to the stud terminal and the igniter/sensor are clean and tight. 

c.

 

Make sure that the ignition cable provides good electrical continuity.

IGNITION SYSTEM GROUNDING....    

(Nuisance shutdowns are often caused by a poor or erratic ground.) A common ground is required for the module, 
igniter, flame sensor and main burner. 
a.

 

Check for good metal-to-metal contact between the igniter bracket and the main burner. 

b.

 

Check the ground  lead  from  the  GND  (BURNER) terminal  on  the  module to the  igniter  bracket.  Make  sure 
connections are clean and tight. If the wire is damaged or deteriorated, replace it. 

c.

 

Replace igniter/sensor with factory replacement part if insulator is cracked.

▲WARNING: The ignition circuit generates a 20,000 Volt open circuit and electrical shock can result. 
a.

 

Check ignition cable. 

b.

 

Check external fuse located in the control box. 

c.

 

Verify power (24V) at module input terminals and output terminal to gas valve. 

d.
