Re: Queen coffee CQ MN-2 Heating element
If the schematic symbols are a bit too advanced for what you have seen? what would I say as a beginner?

Re: Queen coffee CQ MN-2 Heating element
B5 high limit switch has a manual reset but the schematic symbols are a bit beyond what I've seen.
Cream Coffee Queen boiler/thermostat part no. 160212-03 is one big assembly.
Pic you see the two switches.Attached FilesLeave a comment:

This might be the service manual, if not it should be close.Leave a comment:

Re: Queen coffee CQ MN-2 Heating element
The heater connections are at the back of the can.
The front of the can has what looks like two thermal switches. One is for temperature regulation and the other is a safety-limit (klixon). I might be wrong because I don't know the difference between AUTO/MANUAL operation of the heater, maybe it has two running temperatures.
I would measure resistance across the heating element, and to the can housing to see if the heater is not open-circuit or shorting to ground.
The two thermal switches should be normally-closed I think. The one on the right might have a reset button you can see, try push it down. But if it tripped then the left one is for temperature regulation and might be stuck on, so another problem.Leave a comment:

I was Ollie today which is a close out / surplus outlet store I do not go in there to often because you find things that you should not be tempted by but that is a another story
I saw a small space heater that used a wire type of heater element which I been looking for a while but not really hard mind you but when I saw this I grabbed it I going to go back tomorrow and buy the last one that is like the one I bought today because I need the heater element and the ceramic insulators and more of heat element wire because this one has two different wattage settings one 1300 watts ( tap... -
I've got this circuit that I've been playing with on a breadboard. I'm not happy with it mainly because the MOSFET gets too hot and generally controlling the temp of the heating element with the Arduino has proven to be a little more cumbersome than I would like.
What I would like to know, is what is the best way to set up a circuit like this? The heating element is just a PCB and its going to be mounted under a 3D-printed enclosure that a lizard will use to warm his belly.
This is the general setup that I have now.
This is what the... -
Hi guys. I have an question. Overall i am currently selling my house ( apartment with 1 room ) to buy some cheaper with 1 room too, and save cash for new pc in autumn 2024.

Hi!!
Yesterday I was installing a new Wifi thermostat for my domestic gas water heater model Vaillant 242/2-3, and accidentlly one wire from mains touched one wire from the thermostat output contacts. This shut off the heater so I finished installing the thermostat and then went out to check the heater
I found one fuse blown (T2 250V). Replaced it with another equivalent fuse and it blew right away. I measured L-N in mains input and I sometimes got 4K but sometimes, not sure why, I got 100 Ohm...
At a certain point, moving stuff around, I put all wires back in place and... -
Hello everyone.
Some background - I have one of those chinese diesel heaters, which I'm using to heat a garage. Probably most of you are familiar with that units, but here is some basic info - the main heater body is enclosed with the motherboard+sensors unit inside a plastic case. The heater has a glow plug, that works only when the unit is starting (start the fire in the burner) and stopping (make sure to completely burn the fuel inside the burner) and two fans on a single motor. One fan is used to push fresh air in the burner, the other is used to push cold air in the case and...
