Title: Westinghouse Master Water Bath T-Stat Question Post by: 90grad on April 19, 2009, 05:48:07 pm All,
I've had a Westinghouse Master Water Bath for a while now. I actually got it for free! Anyway, I rewired it, to include installing a new thermostat. I never really messed with it until now. The problem is, it won't shut off. The water temp got down to the freezing point, but the compressor kept going. I tried moving the stat probe all over the place in the water. I performed troubleshooting as follows: 1. With the machine unplugged and stat dial at 0, I pulled the probe out of the water. As soon as I turned it from 0, I heard the "click", which is normal operation. I thought, that's good, as it is turning on right away after seeing an ambient air temp of about 60-65. 2. I turned the stat back to 0 and removed it from thewater. 3. Then turned the dial to full cool, with the tip out of the water. I then heard the "click", indicating the stat had turned back on. Then, I placed the tip into a cup of ice water. The water temp was about 36 degrees. Then, I gradually turned the stat down towards 0 and listened for the "click", indicating the correct temp had been reached and the stat was turning off. Nothing. This was a new replacement stat, but I know all these things are now made in Mexico. Do you think it is faulty or is there something else for me to try? Thanks. |
