Temp keeps rising and won't shut off

How big a pool? You normally will not notice a temperature rise immediately. On average, swimming pools will see a one degree rise in temperature every 45 - 90 minutes.

I had the same problem last year, I talked to a spa guy and he stated that the temp sensor was probably covered in bio crud. He also stated that the tub should be cleaned with a hot tub flush. After doing that I have not had a problem with the temp settings.

SOUNDS LIKE A BAD THERMOSTAT OR THE RED & WHITE WIRES IN BACK OF STAT ARE TOUCHING ONE ANOTHER COMPLETING THE CALL FOR HEAT.

If it has an electric radiator fan (not AC fan) The radiator fan is not working. Possible coolant sensor or switch.

All compressors run up to their rated high pressure level, usually listed on the data plate on the compressor or in the manual, then the pressure regulator turns them off. If your compressor is not shutting off it is either not getting to the pressure it takes to get the pressure regulator to turn it off or the pressure regulator is broke and won't turn the motor off. To check which, turn the compressor on and watch the guage that shows tank pressure. If the pressure rises then stops at a level below the rated pressure for your compressor and the motor continues to run, you have a leak somewhere. It could be the tank drain valve, the lines from the pump to the tank, the valve plate or in the piston cylinder area. If the pressure rises more than ten psi above the rating for your tank, your pressure regulator is broke or possibly set too high. If you know how, you can try lowering the shutoff point to see if that fixes it but you're usually better off replacing the regulator.

I Think when it goes back to 33 thats your ambient temp . the temp in the room thats its trying to get down to .
If you set it on 22 . and just ignore the 33 it does it stay on cooling ?

if car shuts off when hot outside, change thermostat and radiator pressure cap.-- heres more-car shuts off when tempurature of engine gets to normal. causes; low coolant, failing coolant temp. sensor, air in water pump. it takes 10-15 minutes to reach normal range. hope this helps! good-day!

its the fan control AFC not shutting off , it comes on at temp rise say 150f drops back to 130f with fan on , burner shuts off fan runs untill temp falls to 100f the fan shuts off in this case it keeps running

why does the cooling fan start working as soon as i start the car and doesn't shut off until i turn off the car?
