My math major soninlaw and I thik that .549 on a 0-2,000 (2K) scale is 549 ohms. If you read that on 0-20,000 (20K) then 5,490 ohms.

So Im guessing regardless if it was 2k or 20k Im still out of range that I need to be so my thermistor is bad.

Thanks!

549 ohms should have read just that on that scale. Try shorting the leads together and see what the reading is. I think your thermistor is shorted.

I would have to have to look at the meter. I assume you are looking at 2K ohm full scale reading. Is it digital or analog?

Nothing wrong with a $20 meter. I paid $16 for mine and it is a great meter for trouble shooting. The cheaper meters don't usually have an auto off switch so you have to be careful to turn it off every time.

My thermister was bad but close inspection showed some wear on the wire going to it. So replaced the complete unit. just cut the old one and taped the new one to it and pulled it thru. Solved the problem. I was a bit worried the wire wear might have shorted and damaged the control board but I lucked out this time..
