in another thread Evo posted a good source for the flame rods and spark plugs for the Sprint 2000. i bought two spark (one for each dryer) and one flame rod - lots cheaper than from M&R.
for some reason i have a bunch of failed electrical connectors on our SMC valves (Gauntlet 3 and Challenger 3 have them on the printheads) - i bought these to replace the connector instead of the whole valve: https://us.rs-online.com/product/smc-corporation/v111-5loz/70399581/
its $20 instead of $90
I believe Auburn is the manufacturer of the flame rods/spark plugs. Luckily they are used in HVAC so not super difficult to find.
The one thing I like about SMC valves is how modular they are. You can order every single individual part.
(which can actually make ordering the whole valve difficult) They even sell rebuild kits if you ask hard enough and wait 4 months for Japan to ship.
Odd on the electrical problem with the valves. We've had every other problem with them but not that one haha.
