if it is not working or not working right, the on switch might be off, the breaker may have tripped, the thermostat might be set wrong, and the filter might be very dirty, the air ducts might be physically blocked or the dampers might be closed. if you have checked these items and ...
If the furnace won’t produce heat, you can check to see if it is getting power by moving the fan switch from the “Auto” position to the “On” position. If the fan comes on, then the furnace is getting power. The likely issues then are: ...

When it comes to the faulty fan limit switch, resetting it might fix the issue. If the blower continues to run after reset, the switch should be replaced with an original part. Thermostat Issues Installing the wrong type of thermostat can create many problems with your furnace. Before you ...
It’s the job of the high-level/high-limit switch to shut down the furnace if the temperature in the combustion chamber reaches a certain temperature. This excess heat can be caused by a leak in one of the combustion chamber tubes or by the improper exhausting of the hot air (which ...

Addressing this consideration may limit any choice of heaters to the point where the overall system cannot readily be made in a cost-effective way. Also, the sealed electrical heater feedthroughs (through the furnace chamber wall) tend to cause microwave leaks. Yet further, any sharp metal ...
In Mode III, the programmable controller will respond to a signal received from a low-low level switch (furnace feed chute is empty), by stopping conveyor C-14 with feed on it and emptying the reversible shuttle conveyor C-15 in the last bin 4a or 4G of the group it has been filling...
Although the variable reactor 16 has been shown as a single pair of thyristor switches, it will be appreciated that other configurations could be used for variable reactor 16, such as a multi-stage thyristor switch for example. Alternatively, other types of power semiconductor switches could be ...
