Hunter Wireless Rain Freeze Clik Irrigation Rain Sensor Repair - Changing out the Hygroscopic Discs

[@lowprofile2412]

Hi Phil, I ordered some washers from you today. I’ll check back after they come in. It was really easy with your links to eBay, and great KZbin post. Thanks, Joe Edit: I received them yesterday, installed and working great !! Saved me a lot of $$

[@philinapex]

Glad to hear!

[@LunkerFishing]

I just installed the discs I bought from you and it rained this afternoon. Everything works like new again!

[@Jakeeandsally]

Hi Phil. I received the disks from your eBay store and installed per your instructions. Works like a charm. Thanks so much for your help. Great job!

[@ryanhodo]

Thank you sir. Bought the discs, wasn't sure how to dismantle it to install them. Didn't want to pry on it and break it. Appreciate your tips!

[@herbertlindblom2426]

Thanks ! I just installed the disks and the rain sensor works again.

[@e.a.p3174]

Unfortunately with Hunter you can’t change the batteries. They are supposed to last about 10 years according to Hunter, I seen them fail after 5.

[@joeesposito5101]

How often do they need to be replaced? Great video! Thanks 👍🏻

[@jozsefmajdan1125]

Thanks for sharing this! Perhaps, is it recommended to pull these disks off and store for the winter or leave it there and isolate it in a plastic bag for instance?

[@agilis1]

Phil can you confirm that the test button ceases to operate if the cork discs are wet due to the expansion of the cork? I had to return a WRF-CLIK b/c of this reason. The replacement once it got wet, did the same thing. No where in the manual, nor Hunter Industries, told me this. They said the button should work even when wet. So far this has not been my experience. Can you confirm?

[@user-xp7ye7tt5o]

Hi Phil excellent video thank

[@jamesskurski711]

Does it matter which side of the discs are oriented? Should the smooth side be up and the grooved side down?

[@devincarrasco2443]

How do you change the battery?

[@rhd4444]

So glad you sell these replacement washers - less expensive than replacing the whole unit but I may have to even do that soon because my unit came with the house built in 2002 so it's the old style with the wire antennae. QUESTION: when I took this old sensor apart there were 7 discs not 8. Is that how many the old units had? If I put on 8 it immediately turns off the receiver even at 1/4 inch? Any ideas?

[@philinapex]

If it is a Hunter sensor, most likely there was 8 discs. It could be possible that two of the discs have fused together over the years so it appears like you only have 7. Regardless, if you are having issues with it turning off way too quick, you can always try removing one of the discs. or if you have a sensor with an adjustable cap, you can just go up to the next higher setting.

[@timrdude]

Is there a replaceable battery, should the LED light uP?

[@ismartinezjr1]

I just replaced my disc with your kit, the rain sensor is still showing active on my pad. Any ideas?

[@patrickmcmorrow1605]

How can I buy a new spindle for the discs? My spindle will not stay up in the cover! Thanks, pat

[@TOPJ76539]

Is there a battery inside this unit?

[@rsheldon86]

I have a Wireless Solar Sync that includes Freeze Click technology. I'm guessing the Freeze Clik sensors are the small discs in the spindle button portion of the WSS? If so, how can they be accessed? They look dirty too.

[@crazyxfish1633]

What happens if it doesn’t work? I changed mine and the hunter sensor still shows wet.

[@williamderr9951]

brass ring sticks to top even when disc are dry

[@peterprince4452]

I ordered your disks, without a washer, before I opened my sensor (it was raining). After I opened my sensor my disks were not too bad, but I could not find a brass washer. My sensor is about 3 years old. Did Hunter make some sensors without a washer?

[@peterprince4452]

I received my replacement discs in the mail in just a few days and took some time to understand how the rain sensor works. I took the parts out of my sensor, including the discs and the center spring . I washed the chamber out thoroughly. It was full of tiny critters and debris. You may need a tweezer to replace the spring back in the center. I placed the new hydroscopic discs on the spindle, keeping them dry. If they get wet, you will probably need to let them dry out before they will assemble properly. The way the sensor works is: when the discs get wet,, they expand, pushing the assembly down, operating a switch in the bottom of the sensor, transmitting a signal to my remote receiver next to my Hunter Irrigation controller, turning it off. My Rain-Clik works GREAT again. BTW, my sensor did not have a brass washer. Thanks!

[@southeastirrigationsupply7943]

All Hunter Sensors should have the brass disc... if you did not have one in your sensor, it must have been inadvertently left out during manufacturing. You can easily buy one at the hardware store if you want, however, it probably will work fine without on as all the rain bird, toro, and irritrol sensors do not have them and they use the same discs.

[@Computergk91Gaming]

our rain sensor was install in September of 21 how often do you recommend to replace the disc

[@silverfoxOct_67]

Phil, thanks for posting the video. It is a wired Mini Clik. Is replacing the disks the same concept as well? Do you have an email I can send you a pic of mine? Thanks.

[@southeastirrigationsupply7943]

The Mini-Clik discs are about 10x easier to change out than the WRFC in this video. First make a note of the rainfall setting your mini-clik cap is set to. Simply twist the adjustable cap from the top of the sensor and remove the cap / discs / washer / spindle assembly. You can then pop out the spindle from the cap and change out the discs. That's it. Put the cap assembly back together and lock the cap in at the desired rainfall setting. Use either of the links at the top of this page to go to my ebay store to order the replacement discs or the discs plus the washer. If you look at this video at the 0:15 mark, you will see him remove a cap from the mini-clik. kzbin.info/www/bejne/rKmZq3qEhaaje8U

[@silverfoxOct_67]

Phil, Thanks for getting that out to me. Installed with no issue. Please stay safe.

[@rayland8553]

Will it also work on the wire hanging down version? Thx

[@nskmda]

any way to replace the dead battery on the sensor?

[@lowprofile2412]

No, not user replaceable

[@nskmda]

@@lowprofile2412 thanks. tho it kind of sucks... 😭

[@womanofsamaria]

When I click on your Ebay disc links, I receive a message, "503 Service Unavailable". Please advise? Thank you!

[@southeastirrigationsupply7943]

Sorry about that! We had to make some changes to our store recently. The links have been updated!

[@88Petry]

How do metal discs act as batteries? Clearly this is what is used. I have never heard of this type of battery before.

[@southeastirrigationsupply7943]

The discs are not metal, nor are they batteries. They are made from a hygroscopic fibreboard that expand when they get wet.

[@Broxty]

Wtf lol?

[@FU-vh2qh]

Is there a spring under the disc ? Or it’s just so happens I had a spring appear in my work area

[@southeastirrigationsupply7943]

There is a spring under the spindle / disc / cap assembly. just drop it back in around the vertical post in the body, then put the cap assembly back in.

[@tiggerm7244]

How do you test battery to determine if it is toast or working? New to home with sensor installed.

[@southeastirrigationsupply7943]

See page 14 of the manual www.hunterindustries.com/sites/default/files/OM_W_Raincliksensor_dom.pdf

[@rickny1971]

Can the discs on a standard wired RAIN-CLIK (not mini) be replaced?

[@southeastirrigationsupply7943]

Yes, the stack of 8 discs can be changed out the exact same way as shown in this video.

[@melvanderbrug8683]

I can’t find your website or eBay to purchase the discs and no one seems to stock them.

[@southeastirrigationsupply7943]

Here is the link to my ebay store: www.ebay.com/sch/southeast_irrigation_supply/m.html?_nkw=&_armrs=1&_ipg=&_from= Let me know if this does not work for you.

[@Broxty]

It's literally in the description.... maybe you should hire someone to do this work, seems out of your abilities.

[@pattichmura2777]

My sensor stays RED even with 10 days of no rain. Could this be the battery or discs or something else?

[@southeastirrigationsupply7943]

Could be either... IF the discs are permanently swollen, they could be holding the switch down causing it to stay off... Or it could be a battery or wireless transmission issue also. If you take the cap (with the discs) off and it goes to green, it is the discs.

[@paullouy3538]

Is there a spring on the post inside the rain clik?

[@southeastirrigationsupply7943]

I believe that all of the rain-cliks have a spring under the spindle / cap assembly. The mini-clik does not have a spring.

[@dennishansen3585]

@@southeastirrigationsupply7943 Mine is a rain clik with the spring. How do you get the assembly to stay in the little "tits" that go into the spaces with a spring pushing up on it?

[@imjacobyournot]

how do you change the battery

[@southeastirrigationsupply7943]

Unfortunately the battery is not serviceable.

[@glendaromero7505]

How do you know if it needs a new battery

[@southeastirrigationsupply7943]

This is from the manual online for the Hunter Wireless Rain-Freeze Clik: Battery Life The Wireless Rain-Clik transmitter is designed to operate for at least 5 years with its sealed, maintenance-free battery. The transmitter is available as a replacement part (WRCLIK-TR). Should you need to change the transmitter, the receiver will have to learn the new transmitter address. To Check the Status of the Battery in the Transmitter 1. Press and hold the quick response spindle at the top of the sensor. 2. Within a few seconds the LED light on the bottom of the sensor will briefly flash. 3. Release the spindle and the LED light will flash again. If the LED flashes, the battery in the transmitter is good. If you are experiencing problems with your Wireless Rain-Clik sensor, follow these simple checks first before assuming the unit is defective and replacing it.

Unfortunately, the battery is sealed under the potting. If the battery dies, you need to change out the whole sensor.
