The element and thermostat in a Wolf warming drawer
Two things decide whether a warming drawer holds its temperature, and the lowest of the four presets is the one that exposes them both.

A single element rated at 450 watts does the heating, and a thermostat decides when it runs. Proof asks least of the two, which is why it is the preset that gives way first — useful information rather than a worse fault. Wolf Pro Repair Denver takes it from there, on (720) 649-6641.
A modest element and a thermostat
There is not a great deal inside a warming drawer, and that is rather the point of it. One heating element at 450 watts, a touch panel hidden until the drawer is opened, and four presets: proof at 100 degrees, low at 150, medium at 170 and high at 190, each adjustable within a small range of its own. A rack, a removable pan and full-extension glides finish the inventory.
Why proof goes first
The element either works or it does not, but the thermostat has to make a judgement, and that judgement gets harder as the target falls. Proof asks the drawer to hold a temperature not far above the kitchen it stands in. On a cool morning the manufacturer says outright that the room may stop the thermostat turning on, and points the owner at the proof light rather than at a breakdown. What we usually find follows that line: drawers reported dead on proof and perfectly willing on high, where the gap is wide enough that no borderline decision is involved. When high fails as well, the element comes into question, and that is a different conversation.

Before you call
-
Watch for the proof light
No heat on proof is answered in the guide by room temperature keeping the thermostat off. If the light is lit, the drawer has accepted the instruction and the room is the variable.
-
Give it the preheat time
Fifteen minutes on low, twenty on medium, thirty on high, and none at all for proofing. A drawer judged before that has not really been judged.
-
Find the shut-off interval
The timer arrives set at four hours and can be moved down an hour at a time. A drawer that has quietly reached the end of it looks exactly like one that has died.
-
Rule the supply out
Nothing at all on any preset sends you to the fuse box, the breaker and the plug behind the cabinet before anything inside the drawer is suspected.
If those read normal, the fault is behind a panel and the next move is ours. Wolf Pro Repair Denver, (720) 649-6641.
Falls in the band
Warming drawer work sits outside every band on this price list, and no band from another appliance is stretched to cover it. The figure goes in writing once the fault has been named, never ahead of it.
