NOTE: Underwriters Laboratories requires a fan interlock circuit to insure the blower remains operating whenever more than one sequencer is used. The fan interlock should be the M1 / M2 contacts of the second or third sequencer. All M1 / M2 contacts are wired to the blower motor so that any sequencer that is energized will keep the blower ON. At the heart of a heat sequencer wiring diagram is a series of connected circles or nodes. The circles represent the various electrical components within the HVAC system, such as the blower motor, the heat pump, and the indoor air handler. Connecting the nodes are lines that represent electrical wires, which are responsible for carrying power.
I was tutoring several students with basic wiring this week so I made this video for them to review. If you where not in class this may be confusing. It is l. With this electric furnace sequencer replacement guide, we will walk you through the process of diagnosing and replacing a faulty electric heat relay. 1—MA1A (A) Air Conditioner Schematic Diagram and Electric Heater Wiring Options. v, 1 Phase, 60 Hertz ELECTRIC HEAT SEQUENCER. Sequencers are necessary for air handlers, heat pumps or electric.
The standard sequencer line is designed to operate in ambients ranging from -40°F to 150°F (-40°C to 65.6°F). The actual sequencer ON and OFF times are 100% checked to the required timings at a 75°F (23.9°C) ambient. The OFF timings are determined after the PTC heater has been energized for a total of five minutes.

It depends on how many heat-strips (heating coils) are installed in your furnace/air handler. E.G., If you have three heater coils, you will need a 3-pole sequencer. Problem: Poor airflow due to dirty air filters causes the furnace to overheat and damage the sequencer, heating coils, fan relay and the safety control switches.

Heat Sequencer Wiring Diagram - A wiring diagram is a graphical sketch of an electrical circuit that shows the affiliation in between the various components of the circuit. Wiring diagrams are vital in the style, construction, and upkeep of electrical systems in homes, buildings, and commercial facilities.
Method 2: Apply Low Voltage. You would find a coil around the heat sequencer. So, you need to apply a low voltage to the coil. Make sure the low voltage supplied matches the requirement of the sequencer. Like, you can see a rate of voltage mentioned on the heat sequencer. So, keep the voltage the same as that.
A faulty heat sequencer is often the reason for insufficient heating; some heating coils may not get turned ON anymore. MORE. Fan and High Limit Switches: auto or manual reset, air stream and surface mount. A disc limit switch is a thermostat that acts to a particular temperature. A furnace has a fan limit switch and a high limit switch.

The Emerson 24A34-3 Electric Heat Sequencer is a direct replacement for most fan/heat sequencing functions. This sequencer features 2 switches and multi-poise mounting. This sequencer features 2 switches and multi-poise mounting. Direct replacement for most fan / heat sequencing functions. 2 switches. On timings: 1-20 sec. Off timings: 40-110 sec.
One of the most common problems identified is heat sequencer failure. Several issues can contribute to the failure of this part: Frequent use throughout the season causing flexing and straightening of the bimetal switch. Sequencers are basic relays that use a heater coil and a bimetal switch. Control voltage is applied to the heating coils.

Open the furnace and locate the heat sequencer. Disconnect the wires from the sequencer. Take out your multimeter and connect the leads to the heat sequencer. You need to connect the probes to the locations where you just removed the wires. Check the reading on the meter. You should get a voltage reading of around 24V.
Below are some common wiring methods: 1. Series Connection. Series connection is one of the basic wiring types, simply connect heaters from end to end as above picture. In series connection, each heating element has the same current (Current = Voltage / Resistance value.). If many elements with different resistance value are connected in series.
