High limit and roll out switch
Lennox Furnace Repair maintenance and installation and services,
Switches can be operated by hand or they can be activated in response to changes in:
temperature, pressure, or fluid movement.
switches can also be activated by an electromagnet as in the case of the relay.
A switch has drawn in the open position, and will not change position until it is switched manually or automatically.

Temperature activated switches:
The metal expands when heated and contract when cooled.
The principle of thermal expansion is used for several control devices that regulate temperature change.
Some temperature disc responds to temperature changes by moving from a concave to convex shape to break.
Consequently a set of electrical contacts, such as in the case of a flame roll-out switch or high limit,
this type of switches are said to be normally closed, or the switch can be constructed to close
a set of contacts on a rise in temperature.
Gas Furnace Thermostat:
Lennox Furnace repair and maintenance and installation and services:
The mechanical thermostat uses a bimetallic strip connected to a mercury bulb that contains a set of contact.
Another thing, how a mechanical thermostat that utilizes a spiral bimetal strip to control the operation of furnaces described like this?
- . As the room cools, the bimetal strips control the glass bulb
- . The mercury in the bulb moves and engulfs the two contacts, completing a circuit.
- This closes the control circuit of the furnace and energizes the main gas valve or primary control module.
- As the room temperature rises, the bimetal strip expands moving the glass bulb in the opposite direction.
- When the room reaches the set temperature, the mercury rolls to the opposite end of the glass bulb and breaks the control circuit.
- The gas supply to the main burners is shut off.

The combination high-limit/fan control contains a normally open fan switch on the right side
On a call for heat, the burners are ignited. as the temperature of the heat exchanger begins to rise, the bimetal begins to rotate turning the front dial with it.
The bimetal strip will first close the fan switch and start the fan motor.
if an overheating condition occurs due to insufficient airflow for example:
faulty fan motor or fan switch or dirty air filter and sometimes low fan speed.
The bimetal strip will continue to warp until the high-limit cut out temperature is reached and then opens the limit switch.
Similarly, when the limit switch is open, the control circuit finally de-energized, which causes the gas valve close.
Meanwhile, the fan continues to run until the fan switch cools to the fan -offset point.

Control modules provide ignition and flame failure protection for automatically ignited burners.
in conjunction with safety limits, operating controls and interlock devices,
these controls automatically sequence with the burner and blower motor, ignition, and fuel valves.
Most noteworthy the control module cycles automatically when the operating control closes its contacts.
Most modern gas furnaces, boilers, and water heaters have evolved from the basic standing pilot ignition system to the electronic ignition module.
We have direct spark ignition or intermittent pilot ignition and hot surface ignition too.
Direct Drive Motor, Variable Speed Fan Motor:
Lennox Furnace repair Maintenance and Installation and services,
First of all variable speed fans enable the heating system to operate at a continuous range of speeds.
the speed of the fan varies almost depending on the dip switch setting and the heating or cooling demand signal from the thermostat.
Also, the same calculations are used to determine the CFM requirements for heating and cooling,
once the calculations have been made, refer to the manufacturers literate to determine the appropriate dip switch setting.
The blower will then vary the speed and torque of the motor to achieve the desired airflow, regardless of the external static pressure drop.
