Temperature way off - by 45 or so degrees!
« on: October 07, 2019, 09:53:13 PM »
I have an older Accurite 5 in 1 that I took down for Hurricane Dorian. I put the batteries back in on Friday and set it back on the post outside. It says it is 114 degrees with a heat index of 158!!!  I removed the batteries, opened it up and cleaned everything. It is now sitting in the house reading 109 with a heat index of 155 for outside. Can I assume it is probably beyond repair?

Thanks in advance.

It sounds like a bad temp/humidity sensor.  Depending on the age of the unit, it can be replaced for about $13 without soldering.

If it's an older unit, you can likely still replace it with the $13 module, but you'll have to cut the 4 wires and solder them into the appropriate spots on the motherboard.

If it's a really old unit with 7 wires, it is toast.

This is a long-shot, but you might try doing a hard-reset of your display.

Take out batteries, move the ABC switch around, put it back on the correct original setting, and replace batteries. If this doesn't fix it, the thermo/hygro chip is bad.

So if I remove the current sensor - which I have done - but still have the same readings on the display, is it the sensor or the display?  And I have removed the batteries and done the reset holding no down the set button and both arrows. Just checking before I order the replacement piece.

And thanks again for the help.

Are all the other readings besides the temp on the display OK?

If you did the reset on the display, that won't fix anything. You need to do the reset on the outdoor sensor...
