(b) 

Check the above items. 

(c) If your machine has a Gray Arm / Dis-arm box. 

Make sure the wires inside are in good shape, free of 

corrosion and not pinched on the bottom of the box.  Green to White would by-pass the switch and arm the 
machine. This would indicate a faulty switch.

 

 

3. Machine runs in DISARM position, but not in the ARM position. 

(a) 

Check for faulty relay. 

4. Machine ARMS but will not fire on the Pull Cord button. 

(a) 

Either the connections, cable or command push button are faulty. Disconnect the 110V Plug from the Pull 

Cord, using a lead wire, with 1” stripped of each end, insert into the Positive and Negative sides of the outlet 
plug.  Once contact is made, the machine should fire.  

If the trap does not fire, then there is a broken wire in the cable or a bad connection in the three-pin plug 
or control box. 

(b) 

If the trap does fire then reconnect the Pull Cord, remove the cover on the push button box and short across 

the two spade connectors. 

If the trap fires - then the push button is faulty. 
If the trap does not fire - then there is a broken wire in the Pull Cord or a bad connection in the three-pin 
plug. 

5. Trap fires by itself. 

(a) 

Disconnect the Pull Cord and switch the trap back on. 

If the trap cocks normally - then the Pull Cord is damaged or shorted out.  Alternatively, the push button 
switch is stuck in or faulty. 

(b) 

If the trap continues to fire – Check to make sure the Throwing arm is contacting the roller limit switch arm. 

The arm should pass over the limit switch with only a small amount of space.  

(c) 

If the machine still fires by itself - check if the relay contacts have stuck together, and if so replace. If the 

relay operates correctly, but the trap still fires by itself, then the roller limit switch is faulty and should be 
replaced. 

(d) 

If the machine still fires by itself – Throwing arm timing could have slipped. Call the Technical Support 

Line for help.
