Title: HE1100 Thermometer
Post by: Radio Tech1964 on December 21, 2019, 01:00:43 AM
Anybody know right off what the length of the thermometer is in these units?
Seems mine is getting inaccurate and the probe length is only close to an inch long and it looks like it has broken somehow.
Just wondered on the length before I order a replacement and it end up being a stubby little critter like I already have.

That is just a Ranco controller isn't it? If so, I think the probe length is closer to 2" long. If it looks broken off, I would make sure part of it isn't still in the well. A 1/4" drill bit should work to clean it out. Just make sure you don't drill through the end of the well.

If there was a chunk of it stuck in the well, I would give it a try with it cleaned out before ordering a new one. Also, if there was no silicone around the wire, that would help make it read more accurate.

Yeah, that's on the blower control and such this is the mechanical thermometer in the front of the unit.
Might be normal but it sure doesn't look like it.  It reads but just doesn't seem right in comparison to my IR unit.
I need to get some better monitoring as soon as I can afford it. Seems like I always get close to doing that then something happens.
Wife broke a couple of toes this time  :-\

If you have a Ranco controller then jut look at that for the temp. Those mechanical thermometers never seem to be very accurate.

It sometime helps with those thermometers if you wrap insulation around behind the dial.

Some of those round dial type temp gauges can be adjusted on the back. There are various models available online pretty cheap. I'm assuming you don't have a digital control, just the old style aquastat? (So no digital temp display).
A digital temp control would be more accurate and easier to read.

I've got a Ranco but haven't replaced it yet. Still using the Honeywell. I didn't think to see if was able to be calibrated somehow. Definitely will look into that in daylight. I don't think those mechanical units are too accurate anyway but in the ball park would beat gross inaccuracy for sure.

I am not sure why I was thinking that your model stove came with a Ranco. If you are going to change it over then I would just do that and forget about the analog thermometer.
