Re: Has my thermostat gone out???

The Low speed on the electric cooling fans have most likely gone out.

Get it up to temp and watch the gauge as it passes 210. See if the 1 low fan ever comes on before both fans turn on in high speed.

Other wise you need a scanner with Bi-direction controls that can cycle the fans to see if this is the issue.
