Error 96 shows 143 F. Hot tub worked fine for 2 days and now it shuts itself off and shows temps higher than they could be.
Well first the manual should say what a error 96 is but i'll save you the trouble , the control is saying heater failure as the water should never be 143 degrees this would burn/kill you if you got in , id look at temperature probe 1st (its in pipe right past the heater ) and next id look at control itself , sometimes water intrusion dammage in controller makes for some "funny" and wrong things to happen
This sounds like a back circuit board to us.

The tub experienced an overheat situation. This may be due to leaving the t stat turned all the way up and not monitoring or the hi-limit sensor is defective. The hi-limit sensor will shut down the heating cicuit if temp gets above 105 D optimally.the fact that the heater light is on is a good sign that things are working at this point.Whether or not a suitable temp(100-103 D) will be arrived at is to be seen. If spa heat kicks off before set temp is reached then replace hi-limit sensor.

It sounds like your circulation pump is not keeping up with the heater. Check for debris in the pump impeller. If this is 24 hour circulation pump, it is probably failing. New units are about $200 US

Since the blower simply takes air from inside the spa cabinet and blows it into the spa, the only solution is to get a heated blower, or insulate the interior of your spa cabinet better.

If the water pump is not circulating water you will want to do a simple procedure called "turning the impeller" You can call 888-997-6366 to be walked through this procedure over the phone.
