Wont heat. - Bunn NHB Coffee Maker

Did you check the associated fuses before doing that?

heat wont go off? what does that mean? turn the gas off and replace the valves if they're broken.

if you have change the thermostat it has to have the option for electric heat the thermostat has o turn the fan on in heat mode on air handlers

Here is how it works:

Not sure of my brand, but when my dryer would continue to run without heating, I replaced one small fuse in the back using Google to find the right part (What Causes Gas Dryer to Stop Heating) and a youtube video to walk me through the process. Instead of a $75 maintenance visit or purchasing a new dryer, I solved the problem for $2.50.
This video worked for me, but you could search for other brands.

Check the water level. If the water is low it will not allow water into the heater core to produce heat. If there is water keep an eye on your temperature gauge It should reach at least 140 to 170 degrees. If it is staying colder than that you have a stuck thermostat which is allowing the water to flow to much and not let the engine warm up. The only other solution is if the fan is not working properly replace the fan relay for you blower.

REMOVE THE BACK AND CHECK THE HEATER FUSE AND THE HEATING ELEMENT-MIKE

have you checked your fuses

In the back of the unit there is a recessed reset switch(red) Depress it until it clicks.

you could remove and bench test the theromostat. my kenmore would not complete the circut to heat at all with a faulty thermostat. Just use a jumper wire to bypass it and test it THERE WILL BE NO SHUT OFF COULD HEAT UP TOO MUCH IF LEFT RUNNING.
