I've got the sensor ordered and will find a local electronics tech to do the soldering on the board. I'll keep everyone updated as to the status of the project and I thank everyone again for the support.

The good news: Went out in the freezing snow this morning and tool the panel off to access the spa pack and the heater. I let the tub cycle for four or five minutes and the temperature at both ends of the heater were the same as the heater right next to the high limit sensor so the heater element appears to be aligned correctly. The bad news: My board has the sensor soldered directly to the circuit board. I did some quick Googling and found that the soldered sensor is no longer available, and that I need to buy the sensor that plugs in, remove the circuit board plug, and solder. This will definitely wait till better weather. Is my approach the sound one? I do plan on keeping this unit for an extended period of time (no plan for an upgrade) and want to make it as reliable as possible. Should I replace the sensor or just look at a new spa pack? Purchase a new circuit board (if available) that utilizes the plug-in high limit sensor? Right now I'm into this tub for exactly the cost of a pressure sensor and I would feel ok in investing in whatever it takes to make it reliable. If the board thinks a new spa pack is the logical choice, what is a good recommendation? Thanks again. Edit: If I need to purchase or send off the board for repair, I would gladly send the work or purchase to contributing members of this community.

Got a bit of snow last night and today here in Northern West Virginia, so it may be a day or so till I get cooperative weather for a disassembly.

The cord was installed by the previous owner's electrician and does not have a GFCI in the cord itself, but I do have it plugged into a 15 amp GFCI outlet. Is that adequate or should I invest into a 15 amp cord that contains a GFCI?

Wow. Thanks for the advice. I'll be running through this procedure in the morning and be back for an update for the board's "body of knowledge". Mike

Hello. First time posting but have spent a lot of time over the last day reading. Lots of product expertise here, so I hope you all can assist. I received a free hot tub from a friend who purchased a house and wanted to pass a tub that came with the house along to someone who would use it. It is a very well maintained Solana X (Model number X1D1677) manufactured 1st quarter of 2002. I spoke to the original owner who said it had been his since new and had taken good care of it. However, he did document the same problem I am experiencing during his last year of ownership, lack of adequate temperature. Once I got the tub home, I did a system cleaning and implemented a Cleanwater Blue chemical pack that worked quite well. I should note the tub is set up for 115v 15amp. Everything appears to be operating correctly (two-speed pump, heating cycle, etc.) but the tub does not come up to a decent operating water temperature. Even at its highest setting, the water is never hotter than 99.5 degrees measured with a digital thermometer. The tub appears to run though correct heat cycles (heater/circulation pump on and off). The tub display shows a consistent three blinking LED display that indicate a flow problem. I have replaced the pressure switch with no effect. If the tub is running on a heat cycle with the control panel set at a high temperature, I can back the temperature reading on the control panel to below 99 degrees and the heating cycle shuts off. I've attached some pictures of the circuit board and model numbers. Thanks in advance for all the help. Worst case I think I can justify a new spa pack if necessary based on the condition of the tub, but wanted to try troubleshooting first. The previous owner had the pump replaced in 2016 or 17. Mike
