It didn't fix it, but the newer element may be packing more punch than the older one. Now it might be a difference in elements - I replaced the burner on the spot that the new control serves, some time back to see if that would fix the lack of heat on anything less than the Hi settings. Med Lo on the old control, equivalent to Lo on the new control. That is, the new control set on Lo is an equivalent rate of boiling as the old control set on Med Lo. Pretty much the same as on Hi and Simmer, but the new control burner is about one full setting hotter than the original, on Lo through Med Hi. I retested the profile on the new control, and it remains as before. Which is fine, one less thing to go wrong -). It's identical to the photo on the right, the RBE-533. Oops, meant to say it's probably 1975 version. Not quite as smooth as the original, but good enough to go. I cut them down some more and they took most (but not all) of the roughness out of the new control. I didn't have to completely disassemble the front panel to remove them, though. I might disassemble it one more time to make sure that the replacment stainless screws I used (I had to cut them to size) are not the cause of the jerky control movement. I must have taken the control panel apart about four times getting everything back into place.
I suppose it's ok as long as I remember that the two big burners act a bit differently at the mid-range settings. It has a bit of a different profile than the stock remaining control on the rear 8" burner, with the Med Hi and Lo Hi on the new control being significantly hotter than that of the older stock control. But in between is a scratch catching kind of action that bespeaks poor workmanship. There are the expected detents at Simmer, Hi, and Off. To my dismay, the action of the control was anything but smooth. After about an hour I finally got it in place, and restored power to the range.
The replacement control looked fine, so I set about installing it toot suite. Complicating matters is that the sealing of the front control panel against spillovers from the range is inadequate, so most of the screws were rusting in place and needed to be replaced once they were coaxed out of their spots. There's a certain order that must be followed to access the wiring and front controls, and woe unto he who ignores it.
Being a compact appliance, a drop-in 30" range, this process is probably more difficult than on a full size range. I got the replacement infinite control for the malfunctioning 8" burner this afternoon. I started this discussion over in the Radiantube thread, but figured it would be better to start a new one.
