Is your spa wired for 110Volt or 220V?

SOURCE: THE ERROR CODE READS SN.

Did you replace both temp sensors or just one? Did you make sure that the new sensors are the same model? If you did replace both sensors with the correct ones, the main board is bad and will have to be repaired or replaced. The actual manufacturer of your controller can provide limited technical support for someone who has the ability to use a multi-meter and test a few components at the spa over the phone.

After refiling a spa, typicall the water is below 50 degrees F. Spas have a freeze protection in their programming so that when the water is that cold, the pumps run constantly to keep it from freezing. It will correct itself

Heat pump?


There could be several issues at work here.


  • First, is the heat indicator light showing on the topside?
  • Is the pump running but temp is not rising?
  • Any error codes displayed on the topside panel?

The drop in water temperature could be caused by a faulty temp sensor or faulty high limit sensor.

Check those items out and see what you come up with.

OH error QCA spa High jets work and heat


OH is the overheat code.

Your spa temperature is set above 108, or your thermostat is faulty & not reading correctly.

vulcan bonaire comfort control External natural gas electronic ignition 2004. ISSUE: Fan blowing only cool air continuously. Forced to kill power to stop it. model is one of the following. MB514E,20E or 30E. Going by mech drawing parts list. i can confirm what type of sensors i have cleaned with very fine sandpaper. flame sensor PN 5441603SP and IGNITER ELECTRODE PN 5441602SP The fault code i see is described as the following. There are x4 LED's. Sequence Left to Right. LEGEND: 1 Flame Sensor 2 Pressure switch 3 OverTemp 4 Diag. R Red G Green S Solid Colour B Blinking LED Behaviour. In order 2RS & 4GS Until i hear ignition. 2RS & 3RB Duration: split second 2RB,3RS & 4GB Duration: split second 3RS & 4GB Duration: Until it has completed blinking x4 times. 3RS Duration 4 seconds Repeat last two mentioned behaviour. in my own opinion, as a safety feature, the unit thinks that it has overheated or is about to. so kills the gas and force feeding cool air to heating components to save it from frying. Does this mean i have fault 04 if so does this mean i may have a faulty igniter or flame sensor or maybe a faulty as described in the mech drawing SWITCH OVER TEMPERATURE 120 degrees celsius. Am i correct here? Is this the over temperature cut out switch? if no one can really pinpoint which part requires replacement, can you at least, in sequence advise which parts to purchase? so then ill just try my luck. i wonder how to properly test if flame sensor, igniter, over temp etc is faulty with a multimeter. do i just perform a continuity test. I wonder what other parts can i test related to this fault im getting.
