I have a Laars Litel LLG 175 N pool heater. For a while the red LED on the control block would stop flashing and it would stop firing. I jiggled some of the wires and the light would start flashing and t would run again. Now it won't run. I've tried removing each spade terminal and cleaning it but so far, no luck. Any suggestions?

It may be a loose solder on the circuit board where the spade connector is set into the printed board. Not easy to see but there may be a hairline crack. I've repaired this issue with a small soldering iron. From the factory wires are secured by zip ties or some sort of fastener, and pulled tight. This sometimes does harm to the board. That red light may have some small letters next to it on the board indicating a fault, and you moving the wire was actually a loose connection that reset it. And the loose connection had nothing to do with the main issue at hand. The red blinking light may be a trouble code also. Count the blinks, or if continuous, may give a fault code. Most pool heaters I've worked on have issues with high limit, meaning the unit faults due to overheating. And many times I've had the maintenance guys back flush at the pool filter/pump system, cycle off the heater(furnace) at the main power disconnect or breaker, and power it back up. Simply turning off the switch on the unit may not reset it. Be safe and ensure all wires are place back to their original position and that all voltage is turned off when servicing. And that all run capacitors are properly discharged before servicing. Hope this helps!
