Question about Waring WMK300 Professional Belgian Waffle Maker
I have the same problem as posted on here. The light comes on and it doesn't heat up. This is after one year of use. Is there a solution or do I have to buy another one?
The same thing just happened to my waffle iron. It worked great for a few months and then no heat.
I took it apart and found the problem. Waring used a thermal fuse instead of a thermostat. The fuse is located between the waffle iron and the stainless cover. The issue I saw is that cooking oil (spray) gets in between the cover and griddle and soaks into the insulation covering the thermal fuse. The oil heats up inside there and shorts the fuse.
Replacing the fuse is easy and it is available at Radio Shack for $1.70 (part number 270-1321). It's a 442 degreeF.
The hard part about this job is diassembly and reassembly. I had to take the entire iron apart just to get to the fuse. It took about an hour to take apart and an hour to reassemble. Changing the fuse took 5 minutes.

Jim's advice worked perfectly. We went to Radio Shack and bought the part and the waffle iron works perfectly fine now. Thanks Jim!

The most common reason for not heating up is because of a blown thermal fuse.
Apparently the controller lets the iron get too hot or the fuse is out of manufacturing tolerance - and so the fuse opens.
The green lamp is normally lit when the relay is off and dark when the relay is on. When cold, the relay normally turns on within a second of power-up (switched on). During power-up, the green (ready) lamp should flicker on, and then as the relay clicks, go dark. If the green (ready) lamp does not flicker, the fuse is probably blown.
The fuse is clamped inside the bottom clamshell in silicon tubing. A replacement fuse (240°C) can be purchased from many sources. The fuse should be re-attached to the wires with new all-metal crimp fasteners.
If the iron is getting too hot and blowing thermal fuses, you may be able to avoid this failure by keeping the thermostat set lower. (Turned a bit counter-clockwise.) If the waffles are no longer dark enough at the ready beep, you may have to use manual override by watching the steam and smelling the waffle.
