Gecko High Limit Probe/Temperature Sensor - NO LONGER MANUFACTURED NOW WHAT!?

Okay so I'm a beginner and I am doing all of this on my own, but I'm a quick learner and I DO NOT QUIT so please bare with me and help me out! I can't seem to find a YouTube video or answer on google on my own so I'm finally breaking down and asking for help, which I rarely bother other people for help...

Okay so I've managed to fix all the leaks and was enjoying my hot tub when I got the 3 blinking light error and it stopped heating up so I read up and realized it was either the Tecmark Pressure Switch or the Gecko High Limit Probe/Temperature Sensor - 9920-100150. At first I think it was just the Pressure switch because I could pull the wires off, flip the breaker and reset it and enjoy the hot tub again for a few hours before it would "trip" again. Unfortunately there was a small drip leak on the underside of the heater tube by the ground which I also learned doesn't tickle when you touch it (so yes now I kill the breaker before I do anything). Like I said, I've learned A LOT, unfortunately the hard way! But I am DETERMINED to fix this thing!! It is my PEACE!!

SO I've replaced the Tecmark Pressure switch, the bad news is that water drip made the Gecko High Limit Probe/Temperature Switch get wet and disconnect itself from the silver heater tub and then it slide out of the actual part where it's connected to the motherboard which this unit is older so it was soldered onto the mother board, the new replacement parts are all just clip on's... so I need to know is there a way to bypass this completely? I've watched other YouTube videos of other brands where they bypass the high limit temperature switch because some people want it to go over 104, so I feel like there has to be a way to bypass this rather than me having to buy an entire new board or is there somewhere that sells OLD parts that are no longer manufactured? I need part number Gecko High Limit Probe/Temperature Sensor - 9920-100150. Which they say no longer exists, they do however show something that has a similar connector but is on a wire and probe ending but not a sticker, so I'm not sure how that would work?

Any advice is greatly appreciated, I'm doing all this myself and I've worked hard, I've rebuilt the entire motor, all new seals, impeller, fixed all the leaks in the pipes, and replaced the Tecmark Pressure Switch, I feel like I'm down to the last piece and I just want to bypass it.

When I turn the hot tub on everything works fine it flows, but the red light on the mother board is light up and the 3 lights are still blinking on the panel so it's not going to heat up after replacing the Tecmark Pressure Switch. So I need a way to bypass this Gecko High Limit Probe/Temperature Sensor - 9920-100150 that is no longer manufactured PLEASEEEE someone give me some guidance!?

 

Hello, please share what fixed your issue, I have the same problem! Thanks in advance!

 

Unfortunately.
your unable to"doityourself".
Unless your have de-solding and re-solding abilities.
The hi-limit sensor you hold- the soldering posts are broken off in the circuit board. The circuit board needs to be removed, repair's made, then the board replaced in the control box.
Yes- your correct- the part is no longer available, but I do have a couple left- I do hot tub repair's.
