If the thermostat is open, the ohm reading will be O/L.
That will depend on the setting of the meter switch and the circuit connected to the component (if there is one).
When you say the furnace is still running, I take that to mean the fan and not the actual flame portion of the furnace. If this is correct, you either have a fan relay that is sticking closed or your tstat is bad. == == == == There may be a very slight time delay the the thermostat before turning off the furnace, but if you are sure that you have turned the thermostat off and the fire continues to burn, you have a serious problem. Have it checked out. The gas valve may be sticking in the open position. Regards
Even if the thermostat is in another room, you are releasing some heat out that open window. This means that the furnace (or boiler) will have to run longer to make up for that loss of heat, and the room in which the thermostat is located will take longer to come up to the set point of the thermostat.The HVAC Veteran
What is open rollout mean on goodman furnace?
Could be that the thermostat is stuck open, new thermostat fixed my 2001 Dodge 3500. If your temperature gauge is not reading warm enough, could be the thermostat.
Is vehicle actually overheating? Could be a bad temperature sending unit or gauge Check temperature with a thermometer If thermostat does not open vehicle will overheat
You will need a digital multimeter that can measure DC voltage for an accurate reading. Open the hood and connect the positive and negative multimeter leads to the positive and negative battery posts. Turn on the multimeter and make note of the battery voltage you have before starting the engine. The battery needs to be fully charged to get an accurate alternator reading. A fully charged battery should read 12.68 volts. Assuming the battery is healthy and fully charged, start the engine and let it idle. Make note of the multimeter reading. A healthy alternator should read 14.2 Volts. Now with engine still running, turn on the headlights and turn on the heater blower on high. Multimeter reading should stay above 13.8 volts. If you are below these numbers you may have a tired alternator.

None.AnswerIt depends! A capacitor is an open circuit, yet a.c. current flows quite readily. And d.c. current will flow for a very short period of time.
The open hearth furnace.
In 1865, the French engineer Pierre-Γmile Martin took out a license from Siemens and first applied his furnace for making steel. Their process was known as the Siemens-Martin process, and the furnace as an "open-hearth" furnace.
If the temperature gauge is reading below normal operating temp after driving a little while it may be that your thermostat is stuck open. I replaced my thermostat and it fixed mine.
