I have a Hotpoint TL21 and as per the first lline below. The guy goes onto explain in great detail. However It seems none of his scenarios fit my Hotpoint. The supplier is less than helpful (More on that later) but for now I am trying to edintify the Cycling control thermostat....As the ones that came of were burnt and you cant see if it had a DOT of any colour on it.
The one off the NEUTRALS does not have a dot on the original (That one is intact) BUT the one that fits the live wires is apparently the FLAT Thermostat.
Neither of mine seem to be flat BUT one seems to have gone in and stayed in when I pressed it. The other one does indeed act like a Jar top and comes out!
Quote "Trouble is nobody tells you what to do if you order replacement thermostats that differ in design from the original ones! and most un-branded replacement kits on Ebay come with no documentation! (which is rubbish!)
So let me explain... When ordering a pair of replacement thermostats, If only ONE of them has a dot on it (be it white, blue, red or green) It is usually on the ONE SHOT thermal fuse, with the cycling thermostat left bare.
If you order a kit where BOTH have a different colour dot on, but one has a little pin hole (back middle) this means it is what is known as a 'resettable thermal fuse' and the other will be the cycling control thermostat.
If for some reason NONE of the devices have any dot or markings, then look at the metal plates of the two devices (the bits that face inward towards the elements) you will notice one is completely flat, and the other has a dimple or circular bevel in it (a bit like the quality testing button on a tin lid) The FLAT one will be the thermal fuse, and the dimpled one will be the cycling control thermostat.
The cycling control thermostat is 'usually' the one wired inline with the live wire, with the one shot or resettable fuse wired across the neutrals.
The dots markings on different one shot fuses usually denotes different tripping temperatures
A blue spot = 150C, Red spot = 120C, Green spot = 130C
I hope this helps somebody out there!"
