Checking the Thermostats.

[kenmyfam]

Quick and easy way to check your Thermostats.
Boil water in the kettle
Grab the meat thermometer
Put some cold water into a jug
Add hot water until you reach the desired temperature (140 to 160 degrees F)
Dunk the stat holding it with something.
Watch for the bubbles as the stat opens from the trapped air.
If you can stand the heat or don't mind burnt lips blow through it and as it cools you will find you can blow no more as it closes.
We have 2 thermometers so I check them against each other before I start.

Works for my version of thermostats !!!

Re: Checking the Thermostats.

What I have always done , (at least with car ones) is to force them open a little to trap piece of thread in them and suspend them in a pan ( actually usually a laboratory beaker .. but that's the obvious thing to use when you are in a chemistry laboratory).

Put some warm water in the pan ( beaker) and a thermometer then slowly heat the pan/beaker on the stove (or with a laboratory Bunsen burner)

The thermostat drops off the thread the moment it cracks open! Read the thermometer.

Why don't you just unscrew them and take the thermostats out? It's a lot easier to watch the pin that way.

The less I have to take apart the better in my book !!!
Just my 2 cents though

If you take the vernatherms out and just drop them in a pan of water while it heats, you can watch the thermometer without the tools and stuff.

But the kid's love to watch it this way !!! It's like a science lab to them
