    Ever hear of an air switch occasionally self-activating?

    Hello all - I'm trying to help some friends who have been plagued by a spa air switch that seems to self activate from time to time. I'm wondering if anyone has heard of that before. Their pool is a 10K gal IG gunite, spa alongside using the main 240V pool pump and 240V blower, controlled by an intermatic RC2343PT four position air controlled relay switch with timer, spa air switch installed on top ledge of spa, 30 ft of 1/8" flexible (aquarium style) clear tubing from switch to RC2343PT.

    In order for the timer portion of rc2343 to properly control the pool pump when spa is not in use, the RC2343 must be in "Step 1" (of it's 4 possible steps - wherein subsequent presses of the air switch advances the internal RC2343 relays to create 4 possible combinations of pump and blower on and off). Again Step 1 leaves the pump controlled by the timer. This works fine for awhile, but something is causing the rc2343 to advance to other steps, sporadically, once or twice per week, as if something or someone pressed the spa-side air switch.

    Going back 2 years, I believe they had a similar symptom and they had the RC2343 replaced. Then one year ago they had the tubing replaced. They have no kids, they're away and pool cage is locked, and the pool cleaning service swears they never touch the spa-side switch, yet it keeps happening. Each time I go over there I find the relays in a different step, and of course the timer cannot control the pump properly if the controller is in any of steps 2, 3 or 4. Today I went over and replaced the RC2343PT (again, which was probably stupid but I had observed the enclosure had issues anyway and the tubing compression nut was missing).

    Now I have to go over there again because the new RC2343PT has new issues, so I'll return it for refund if possible (brand new and the blower relay is intermittent and somehow they assembled the timer tripper switch to go ON with red stepper and off with green, which is backwards - ugh). I'm tempted to re-install the last RC2343PT after fixing the enclosure and finding a compression nut for the air hose, but then I'll be back to where I was, with the original problem.

    I don't have a good feel for the air switch model, have not tried to remove it - it's just a white covered rubber plunger at the top, no clicking or anything when depressed, but one hint is that it takes very little pressure to actuate the controller into the next "step". Perhaps about 1/2 inch of plunger travel causes it to actuate. I'm wondering if anyone has heard of the "heat of the day" adding enough pressure in the hose to actuate the switch. This is south florida. Another hint is that despite the fact the hose was a fairly snug (might say very snug) fit on the old RC2343, absent the compression nut the hose was found disconnected a couple times in the past year.

    On the next trip over I'm going to try blowing out the hose to see if water / condensate might be in the hose. Or perhaps a wider hose that is less sensitive? Or a switch that is less sensitive? Perhaps a better controller? I'm looking at the Len Gordon FF1094TC-4 as one possibility if I can't trust the relays in the RC2343PT. Any advice on good controllers of this type (short of a $3K automation system)?

    The friends are out of town for a few months, so in the interim I shut off the blower breaker so it can't come on when in the wrong step, and I'm monitoring the pump remotely using an old smartphone set to auto-answer video calls from my skype account - a clever little free "baby monitor" I though of and folks have posted about around the web - lol.

    Thanks for any advice!

    I have on 3 occasions seen phantom air switches tripping. 2 were do to moisture in the tubing. The third was unknown but we solved it by adapting a larger diameter air tubing.

    Water in the airline. Air switches are notorious for this problem.

    Thanks very much guys for the replies, I'll especially chase the water in the air line angle!

    Any chance that a spa cover is pushing the switch?

    Use some compressed air to blow it out. It's just a common annoyance with air lines.

    Thanks again for the ideas. No spa cover there, but a clever thought! I blew air through the 35 ft of 1/8 tubing today, no water came through but I may need to try a compressor that is better than my 1 gal cheapo. Also need a helper there to watch if "anything" is really coming through - resistance to air flow seemed very high. Then again 35' of 1/8 tubing should pose resistance. I also noticed that although there may not be water in the tubing, the 1" conduit the tubing routes through is FULL of water. That too will take a better compressor methinks, so more to experiment with. For now I leave tubing disconnected from control so timer operates reliably.

    Hi nuttyp, after much searching online I finally found your discussion about the same problem I am having. Every once in a while, i come home and the pump is running. I can tell it was the air switch because the control is at a different step as you described.

    Have you found a solution? I have replaced the tubing, i rerouted it to avoid sun exposure ( in case it was heat build up causing air in the tube to expand) and nothing worked. i disconnected the tubing from the control for now. My next attempt will be to replace the electrical air-activated switch in the controller in case it is too sensitive.

    My indoor whirlpool had one that would turn on once in a while. It finally turned on one day when I was not at home and burnt the pump out. Once they replaced the pump never had the problem again. I guess the switch was bad.
