What does a hi limit switch on a spa do?

This is what a hi-limit switch does. It’s a safety switch that measures water temperature, tripping if it senses a higher than normal heat rise. A good way to check if the filter is causing the hi-limit switch to trip, is to run the spa without the filter for a couple of days.

How do you reset the high limit on a spa?

Or it might need a reset from time to time for no known or serious reason. Simply reset by pressing the big red button on your spa pack. The high limit switch may be housed in a thermowell. If the water temperature in the thermowell is the same as the water temperature in the rest of the spa, the switch is damaged and needs to be replaced.

What to do if your hot tub high limit switch is damaged?

Simply reset by pressing the big red button on your spa pack. The high limit switch may be housed in a thermowell. If the water temperature in the thermowell is the same as the water temperature in the rest of the spa, the switch is damaged and needs to be replaced.

What happens when the Hi limit switch does not trip?

If the hi-limit switch does not trip, then it is time to buy a new filter. (See Filters) Another reason the hi-limit switch trips is for the very reason they were designed; the spa water exceeded an abnormal temperature rise – Refer to Water Gets Too Hot section.

What to do if your spa heater does not heat?

Once they are removed, tape them together; turn the thermostat dial down to the off position, and turn the power back on. Make sure the spa is on the heater/filter cycle and water is flowing from the jets, turn the thermostat dial up while watching the contactor, if it closes when doing this, then re-test the heater using the amp-meter.

What should the temperature of spa water be?

Spa water heats at a rate of 3 degrees an hour wired at 110 volts and 10 degrees an hour at 220 volts. If you did not get a reading at all then continue with next test. Make sure that the heater/filter cycle is on, and the thermostat is turned all the way up doing this test.

Why is the heating element on my spa not working?

If for any reason one of these components fail then the required voltage to the coil will be jeopardized and the contactor will not close in order to send power to the heating element. As mentioned above, it is usually one of these components that will cause a spa not to heat.
