I have a 13 year old propane heater that failed last year and no one seems to want to fix it. It's a Purex Triton Minimax plus. Apparently these have a bad reputation. I had the control panel replaced so those functions operate but now it won't ignite. Last person who looked at it suspects it's a bad gas valve. I get flow indication, I can hear and feel the solenoid on the valve kick in and the igniter clicking but no gas smell and no flame. Pool store was supposed to order a new valve but they got got busy and punted.
If I could order the valve myself online is this a DIY repair or dangerous since it's a gas component. It's seems to be a straight forward remove and replace but I don't know how to check for leaks after tightening the gas lines.
Other option is to just replace the whole unit. It's 13 years old and apparently a troublesome product by reputation. I don't have natural gas so my options are another propane heater, electric or heat pump, or solar. I usually only use the heater in May and September and only plan to keep my house another 5 years so return on investment is a consideration.
