ChiliPad ChiliCube: Internal water tube popped off. How to get it back on?

ChiliPad ChiliCube: Fixing the actual Chili Pad

Wed, 24 Sep 2025 13:21:11 -0700

Just spent $300+ dollars to replace my pad because it started leaking after I washed it. Now I have a pad to play with and try to repair it. Assuming you can find the right medical grade tubing, this should be an easy fix.

I have suggested to the Chili people that they come up with a patch kit for the older or out of warranty pads. The answer I got back was “we are thinking about it”. Which sort of says… thanks for your suggestion; however, we are in the business of making money for our investors.

Question: I need place to buy the medical grade tubing. Any suggestions?

I will then need to figure out how to attach it to the tubing so it doesn’t leak. Any suggestions?

ChiliPad ChiliCube: E3 error code - works on heat but not on cool

Sun, 18 Aug 2019 23:55:06 -0700

My cube works on heat but not on cool - it will give the E3 error code.

I ran it for 8 years without cleaning it and there was a considerable amount of gunk inside the reservoir. I ran the cleaning cycle for 24 hours on the highest temperature and the gunk seems to be gone. However if I run it on cool it will get super hot and give out the E3 error code - also it smells very hot and almost like an electrical fire in there. The fan runs on heat but not on cool. Im comfortable opening it up but I don’t know which part to replace, any ideas?

ChiliPad ChiliCube: Unit blinking 888, won't turn on

Wed, 13 Aug 2025 16:27:54 -0700

The power went out at my apartment a few nights ago and now my cube just blinks 888 with all lights flashing whenever it's plugged in. I contacted the site help and they sent me a link to the Cube power supply repair kit and power replacement guide. Has anyone successfully done this? I tried calling around in my area but apparently no one does small appliance repair anymore. Am willing to try it but not sure I want to spend the money if it's hopeless.

I did it! the guide was very helpful. The only thing I struggled with was getting the wires labeled CN2 and CN3 to unlatch. They have a blue protector that needs to be slide up to expose the latch, and then the metal tab can be pushed to release them-- I used tweezers, but needle-nose pliers would probably work better. Once I replaced the power board I put in the cleaner and distilled water and ran on High for a couple hours. Unit is now back to normal.

ChiliPad ChiliCube: Anyone know thermistor part details?

Tue, 21 Nov 2023 13:57:41 -0700

Does anyone know the specs or replacement part on the thermistor? Mine went bad and I've currently just wired in a resistor to keep it working, but I'd like to be able to control the temperature again with a working thermistor.

Tech support on their end wasn't helpful. :(

ChiliPad ChiliCube: Cleared Code 888/Cube turns on but no noise - not functioning

Tue, 20 Jan 2026 23:16:25 -0700

Hi! I had an 888 code. I followed the instructions and cleared the code. The unit turns on as far as the display board showing the temperature and I can adjust the temp up and down but the rest of the unit is not working (no fan noise, doesn't seem to be circulating water and the temp never adjusts automatically as if it is cooling or heating. I'm trying to determine if there are more steps to attempt or if I need to replace a part. I also don't know which part(s) I'd start with. FYI, the 888 code appeared after our friends at Centerpoint had a brief "lights out" flash and despite me having the unit plugged into a power surge device for just such occasions. Please note I am not at ALL mechanically inclined and while I enjoy learning new things, please keep in mind I'm a 63 year old woman without a lot of fixit experience, so please response as if you are speaking to a - 63 year old woman without a lot of fixit experience. Thank you for any assistance you can provide. Autumn

ChiliPad ChiliCube: Cube’s fan won’t turn on, and cube continues to flash

Fri, 09 Aug 2024 20:56:08 -0700

Wondering if anyone can help me figure out why my chili cube is flashing between the temperature, the temperature I want it to get to, and the 888 flash/setup after a move. The fans won’t kick on. I have a queen “we” and one side I was able to eventually get working, but the other side keeps doing the above. Any ideas how to fix this?

ChiliPad ChiliCube: Replaced fans with Noctua. Why do the fans keep spinning up and down?

Sun, 23 Jun 2024 04:13:31 -0700

I followed the guide to replace the fans with better quality fans and went with a pair of 92mm Noctua NF-A9 fans. I opted to desolder the original fans, snip the connector off the Noctuas and solder the positive and ground onto the original fan cables. The procedure went smoothly but now that everything is reassembled the unit keeps oscillating the fan speed from low to high. It sounds like it's trying to kick the fans to a higher speed and then immediately goes back to the lower speed. What's weirder is that eventually it will lock into the higher speed for the fans but seems to react when I put my hand near the intake vent and go back to the lower speed. I've experimented with it enough times to be absolutely sure that it is reacting to my hand being put near the intake vent. It acts like there's a sensor there detecting my hand, but it's more likely that it's reacting to (very tiny) pressure or airflow differences. It's not like I'm obstructing the intake, just putting my hand maybe .5-1 inch away to feel for airflow. Maybe it's a power/voltage issue?

The stock fans show 12v 0.2A and the Noctua's spec sheet lists 12v 0.09 so they should be requiring less power, right? Now sure what to make of any of this.

ChiliPad ChiliCube: How do I bleed air out of the system?

Mon, 15 Jan 2024 18:20:23 -0700

I’m using a Chili cube to cool a pillow insert. I keep getting a ticking sound in the pillow insert which leads me to think I’ve some entrained air in the system.

I’ve tried a few things with no luck. I’m open to any suggestions.

ChiliPad ChiliCube: ChiliCube will not power on

Tue, 02 Jan 2024 19:20:55 -0700

My ChiliCube was working fine. I travel with it and after my last trip (it was packed in a suitcase in a car), the lights came on momentarily after plugging it in and then nothing. It will not power on at all. Fortunately, I have a backup unit, but it has a habit of shutting itself off in the middle of the night. There is no sleep without it, so any ideas would be greatly appreciated. I hate to have to buy another one.

ChiliPad ChiliCube: Who does repairs on Chili Cube?

Mon, 16 Oct 2023 19:26:21 -0700

Do you if there is someone that repairs these units. In my case, the cube is making a noise that could be a bearing that is starting to fail. I asked the company but they don’t do repairs on out of warranty units.
