Beginner just starting out.

Can anyone please give me some tips or direction?
I am working on this Euro pro F1066 residential/crappy homeowner 120v deep fryer. It seems to work other than it does not heat up the oil at all. I am unsure how to check that black relay thingy.

Video 1 (oldest of the three short videos): https://youtube.com/shorts/26bQU347xPo?is=A2-4PS61RhYYTMu0

Video 2: https://youtube.com/shorts/qyNUdxSlqc0?is=5K3eaw490ybbNinE

Video 3 (newest of the three short videos so far): https://youtube.com/shorts/SGuytCRRSEE?is=miaHzUNdM8Op0rQg

I don't see any voltage on the temp sensor that is submerged in the oil. The temp sensor is attached by wire to the thermostat (or is it called the high limit?). I am attaching three videos. In one of the three videos it shows me checking the voltage of the sensor while the whole machine is plugged in, and also in the same video, I unplug the machine and perform an ohm check on the thermostat (or high limit?) But I do the ohm check incorrectly.

In one other of the three videos, I believe I do the ohm check on the thermostat or whatever it is called correctly. Also showing some photos.

One video shows me performing the short to ground test but maybe i need to try it again with the actual oil-holding pan/shell

What else I've tested so far:

• Heating element makes 11 or 12 ohms
• I tested two resistors for correct resistance
• I pushed on the breaker as hard as I could (these have a little button on the back of the plastic controller)

I know this is just a crappy not-commercial-grade appliance. I realize it does not make monetary sense to fix it, but I'm trying to learn more. Also, a concern is that it works fine and I'm just retarded and making a mistake.

I'm hoping to improve my troubleshooting skills.

Any help much appreciated. Thank you

 

There should be a high temperature cut-off fuse that looks something like this:



It should be bolted on to the bowl. See if there is one and measure the resistance across it. If it measures open then it is blown.

I have spoken to some people before, none of whom are as articulate as you, and they talk about something called a "high limit". Is this synonymous with high temp cut off fuse?

Just to confirm, your image/photo shows three fuses/limits, but we would expect I would only have (one), correct?

I do not know what a bowl is but I'm googling it now. the actual stainless thingy/pot/pan that all the oil sits in is a removable component. Very similar to this attached image

If I can locate it and it is blown that is actually something I may have adequate ability to deal with. If I had known about a fuse this whole time, that would've been the first thing I checked. I figured since it has a breaker thingy button on the controller, I never considered the possibility of a fuse existing

Thanks so much!!!

edit: i'm looking for the fuse but still don't see any

 

I agree with @MrChips. A thermal fuse is the common culprit that kills many small appliances. It's a great safety feature that prevents a fire when all else fails, but they commit suicide in the process.

They're not expensive but getting your hands on the right one, delivered, may cost more than the appliance is worth. Certainly once you factor in your own time. I've got a rice cooker and a couple other things awaiting repair in my basement but of course they all use different thermal fuses. I can't just order a 5-pack off Amazon and be done with it.

Note the thermal fuses are often hidden inside a braided "jacket" of some sort.

I'm still looking but I do not see it so far

 

Hi,
The thermal fuse will be soldered or crimped to you device.
As stated previously it will be covered by a sleeve of some sort.
I mention this because you are not looking for a conventual pull out fuse.
It looks like a thermal fuse attached to the heating element. (Edit).
Good luck, keep us updated.

I know it doesn't look like a bladed automotive fuse or clothes dryer fuse because @MrChips generously sent that photo

This first video is kind of long but if you fast forward to the end i show everything and I think there is no fuse I cannot find it:

This second video was a video from earlier today that I never got around to sharing I believe: https://youtube.com/shorts/zNfzyYLx6zs?si=BjUBEoDw8PXpcEN5 I'm not sure if this second video will actually display a big thumbnail since it is a short not a traditional video

Also im gonna attach the photos of the front of the screen board just so there's no doubt it's not hiding up there either

 

This is a detail from one of your pictures. It looks to me like a wire is disconnected from what might be a thermal sensor (the tube along side of the heating element.)

Newer photo attached

 

I still see nothing attached to the bottom. Do you not see the unconnected wire in my clip? There should not generally be any unconnected wires. And a sensor or fuse needs two connections. Perhaps the picture is misleading and the wire is connected to something?

Another new photo attached

 

I am talking about connecting the two circled items. I cannot tell from the photo, but if the connector on the wire slides into the terminal on the suspected sensor, I think that the way it should be.

 

Hello,

I think that black piece has nothing to do with the sensor.
The sensor probably works on expansion of a substance in the sensor.

An insulated wire would be unlikely to be submerged in hot dirty oil. You are focusing on a plastic zip tie that I used as a pointing/visual tool to draw attention to small objects in the videos

I really would like to find this fuse but I've looked very hard

 

That long thin thing looks like a temperature probe.

The reference to "the bowl" refers to the bath or tub that holds the oil. A thermal fuse must be attached to some part of the device that gets hot by design, but must never exceed a certain limit. So it would make some sense to attach a thermal fuse to the outside (away from the oil) wall of the oil basin, perhaps on the bottom where it will still do its job with a low oil level.

And as soon as I say that, I realize a problem: No oil. You wouldn't want the heater full on trying to heat the oil if there isn't any present. So that almost dictates that a thermal fuse - if there is one - needs to be very near the heating element, to detect if it's dangerously overheating.

We may have misled you. Thermal fuses are very common but it's possible this unit was designed to get by without one. I have a similar fryer downstairs. If I get some time I'll try to see if it has a fuse.

No worries. I just wish I was better at troubleshooting and better at taking readings. I'd like to verify stuff
