    Q:
    How to check and replace a malfunctioning thermostat? Posted by Customer
    A:
    If you suspect a faulty thermostat, test it out before you replace it. To test, submerge it in water heated to its rated temperature (typically 195°F). The valve should fully open at this temperature. As the water cools to about 10 degrees below this (around 185°F), the valve should close completely.
