Now THAT's an interesting and novel proposal for solving the infamous solenoid-amp-sucking problem. You could also put a small tank downstream of the solenoid to serve as an accumulator. This would give you control of the run time/refresh interval.

I've moved on to a compressor fridge, but if I still had propane, I would definitely consider doing this. You can get the timer you need on eBay for like 6 bucks, complete with relay.

If you get the time, can you link a timer thingy on eBay for me? I have no idea what I should be searching for. I can start my education into this from there.

Thanks

Here's one, chosen more-or-less randomly:

DC 5V 12V Multifunction Self Lock Relay PLC Cycle Timer Module Delay Time Switch | eBay

That link won't work for long, so here's an image:

You can find similar stuff on Amazon.
