Promo SM ✋

It is likely measuring the coolant return temp

Options E1 “Min Temperature”: Lowest temperature that freezer can be set to cool down to. -40C/-40F to Target temp. Default: -20C (-4F) Caution: setting the value too low may damage the compressor E2 “Max Temperature”: Highest temperature that freezer is allowed to reach. Target temp to 40C/104F. Default: 20C (68F) E3* “Hysteresis”: Difference from target temperature before powering up compressor again. 1C/1.8F to 10C/18F. Default: 2C (4F) Compressor should stop at target temperature (ie. 4C), and start again when internal temperature is E3’s value above it (ie. 4C + 2C = 6C) E4 “Start Delay”: Time delay protection. 0-10 mins. Default: 0 min To protect the compressor, it will wait that amount of time after being idle/powered off before turning on again E5 “Temp unit switch”: Temperature unit display. C or F. Default: F E6* “TC: T >= -6C”: Do not modify. Temperature compensation (for temp set to above -6C/21.2F). -10C/-18F to 10C/18F. Default: 0C (0F) Displayed temperature = Detected temperature + Temperature compensation Used to match Displayed temperature to what is actually Detected inside the unit E7* “TC: -12 <= T < -6C”: Do not modify. Temperature compensation (for temp set to between -12C/10.4F and -6C/21.2F). -10C/-18F to 10C/18F. Default: 0C (0F) E8* “TC: T < -12C”: Do not modify. Temperature compensation (for temp set to below -12C/10.4F). -10C/-18F to 10C/18F. Default: -3C (-5F) E9* “TC: Shutdown”: Do not modify. Temperature compensation “shutdown”. -10C/-18F to 0C/0F. Default: 0C (0F) I have no idea what this is for. Shut down the compressor when a specific, differential value is met? * Each difference of 1C is 1.8F

Love the fan added with the switch..😊 O wwnt thru the same battle tryn to make mine read out decent. I did find the hidden menu and needed again 4 yrs later and u saved the day. So thanks much. I ended up just knowing what temp to leave it at so the pop would b 34-36°f when they had been left in the fridge overnight. Key is to have stuff cold already as it will take overtime for sure to cool things down. I usually set the warm stuff against the outer walls so it can cool them thru conduction as without a fan like the man says ther is not much convection. It does happen if given enough time. Over all tho. I do have to say I love my little fridge!😊😊 use it in my service van everyday 365 for 4 yrs now. Sips sips the power. 35 watts when running compressor. A 12 volt deep cycle battery being used as a house battery will take Carr of it no problem. I'd think it could even b ran off your car battery for camping or travel for a few days and b ok. I'd say to have a solid car battery tho. Pr at least ur jump pack along just in case. But if u set the voltage cutoff on h3 it should shut off with plenty of power to start the car still.

it's an cheap cooler who care

Thank you for doing the video! I love your mod. I just got a T50. Mine has a USB port so I think I’ll try using it two fans. I also just had a thought that the three temperature settings are for setting offsets for three different ranges of temperatures. On mine the three ranges for offsets would be/are: less than -12C, between -12C & -6C, and offset for temperatures greater than -6C

I really want to do disassembly too, but am too chicken. Is there a service port for evacuating and adding the 134a refrigerant? In the video I don't see anything like a shrader valve as you would on a car for servicing low AC, but perhaps there is some tiny valve hidden somewhere. It specs on bottom of unit indicates 24 grams of 134a so presumably it would be possible to recharge. I tried to kill mine as well by running the model C20 inside car with 120degF heat, and the max operating ambient air temp is 113degF. The compressor stopped, so I brought it inside, let it cool off, and an hour later it ran fine. The rattle noise increased a little bit after this 'death heat test' but by placing a bath towel under the frig, the noise went away. So I guess you had no trouble prying up the operation panel and accessing the two screws underneath?? I wonder how I'll reduce that rattle noise...

What is the average watts per day it takes?

It looked like you had the Fluke temp probs in the ice water. If so, that was the issue. Ice water will always show around 0C or 32F.

Update. This thing is perfect! All offsets zeroed and -20 is -20! It just needs time to settle. So if you’re having problems then you are chasing the temp too much. Basically it’s probably better at keeping things cold than getting them cold quickly (except for my cool mod 😎) Going to do a more gooder video later when I clean my kitchen

E 9... Is the Setting! and I like your fan. Fixing the problem.

Couple extra notes: Please ignore (or get over) the mess in the background- madness and genius seems to go hand in hand. 🤣🤣🤣 I bought the “best” little fan I could. Has ball bearings and not just bushings (hopefully handles the extremes better). Modify at your own risk. And remember you saw it here FIRST. Alpicool should give me millions and millions of dollars for this simple fix, hahahahaha. Take care and I hope this helps you
