GBiers Posted January 30, 2019 Report Share Posted January 30, 2019 I have an Arctic Spa hot tub. Came back from vacation and tried to turn temperature up. Controls do not respond to any action. Shows water temperature only but controls do not respond to any action. Quote Link to comment Share on other sites More sharing options...
Jersey Hot Tub Repair Posted January 30, 2019 Report Share Posted January 30, 2019 Is the hot tub maintaining the set temperature? IOW, is it heating? Do you have blinking dots under the temperature on the display? First thing to try for any hot tub problem is reboot. Power it off, wait 30 seconds, power it on, and let us know what the display says. Dave Quote Link to comment Share on other sites More sharing options...
GBiers Posted January 30, 2019 Author Report Share Posted January 30, 2019 Rebooted but nothing happened. Just shows temperature but there is no response to any of the function buttons. Quote Link to comment Share on other sites More sharing options...
Jersey Hot Tub Repair Posted January 30, 2019 Report Share Posted January 30, 2019 Is the temperature correct? Are the pumps turning on themselves when you turn the hot tub on? Is the tub filtering? First thing to check is to see if transformer is providing low voltage to circuit board. Typically you'd expect to find between 12-14V on the secondary wiring. USUALLY the primary wiring, which would be 220V, will be red and white or red and black. Secondary wiring will typically be yellow or blue. A wiring diagram or a label/sticker on the transformer itself would verifty that. There's probably a glass fuse somewhere on your circuit board that protects the circuit board from over-voltage. Check to see if it is blown.That will prevent the topside control panel from working. Is the topside old? Do the buttons make contact when you press them? Or are the mushy or have they been problematic in the past? Moisture gets in there and will eventually cause it to malfunction. I would also check the wire between the topside control panel and the spa pack. Frequently they are gnawed on by rodents, which might create the problem you're seeing. What kind of spa pack does your hot tub have? Most of the Arctic spas I've worked on have geckko packs. A few photos, model numbers or part numbers would help. If it's a balboa pack, you can disconnect the topside and the tub should default to 80 degrees. Dave Quote Link to comment Share on other sites More sharing options...
