I have a Jandy lx heater and it’s 14 years old never gave me a problem till now. spa water heat is set to 104 but only heats up to 85. So I I have a service light on for temp sensor. I replaced all the sensors 150,132 reset sensor and temp sensor. I restarted the heater and it did the same thing water only heats to a Certain temperature. I went to check and it looked like the reset sensor was tripped to I resented that sensor and let the heater cool off. Restarted the spa and heater now the heater does not turn on because I’m getting the service light on temp sensor again. I checked the board and it has correct resistance. Any recommendation on what to do next?
Jandy lx service temp sensor light on?

Welcome to TFP 
What type Spa do you have? What does the manual say for troubleshooting? It may need a motherboard done or who knows, 14 years is a great run for a hot tub
You may have to call a local hot tub repair guy to come check it out...
There may be another way to go about getting a brand new system..

I changed all sensors high reset low and brass nuds I also replaced the front and rear seal so there is no leaks I turned on the heater and now the blower turns on for 15 seconds then turns off still stating temp sensor service light. Before The blower would not even turn on

your getting there... so the temp sensor is still getting set so that port on the motherboard is either bad or that sensor is... It could be something else though but I have no idea what it could be...
Yes after I replaced all the sensors I knew it was my board. I could not find one new as it has been discontinued so I did research and found JP Engineering online I emailed them and they replied quick he gave me his address and I sent him a check for 150.00 with in one week I got my board back and I plugged it in and wala everything works now. They saved me lots of money...

Nice, so they fixed the board... Do they only do this board or do they fix any board? Do you have a website?

Sounds to me you replaced the hi and hi-hi temp shut downs and not the one used for control. It has two wires (usually black) that go into a 1/2" fitting on the manifold. The other end snakes through the heater and plugs into the control board. Make sure you follow the same routing with the replacement; it avoids high voltage wires.
