Cold weather 32 and below can cause trouble for a number of reason.
1. Water turing to ICE
2. Lubricant becoming sticky or viscous
3. Diaphragm materials hardening
Soulution:
1. Water traps help with excess moisture
2. Clean all internal of lubricants
(Almost all solenoid valves don't need lubricant to opperate properly)
3. No real solution. Most seals lose sealing properties the colder it gets.
