Taking a look at Keeprite, Lifebreath, Lennox and Carrier serial numbers to determine age and warranty

Different HVAC units come with different parts manufacturer’s warranty. Your home owner’s manual should indicate the warranty period. But how do you know how old your unit is?

Here is an explanation of how to read your furnace or HVAC serial number to determine the age of your equipment. 

Below is the unit serial number breakdown for Lifebreath, Keeprite, Carrier and Lennox HVAC equipment for Canada and USA.

You can check the resistance with an Ohm meter to ensure the element is good. The recommended resistance is 50 to 90 Ohms for the flat style element igniters.

Your furnace original Silicon Carbide igniter has most likely been used by furnace manufactures for a long time. This old technology hasn’t changed much in almost 59 years.

They are very fragile, break easily.

Grease or dirt can cause early failure.

although they are available with different ceramic bases, most of the silicon carbide igniters are the same and they fail more than any other part of the furnace

Exact OEM manufacturer igniter replacements

These are the easiest way to replace these Hot surface HSI igniters:

With the same base and same plug as the original they will fit easily and quickly

Take care not to bump the element or to touch it with your fingers.

OEM may not always be the best choice when it comes to igniters.

www.heatingpartscanada.ca offers upgraded nitiride igniters with a ceramic bases similar to the OEM original parts. They provide different plugs to allow models to become exact fit replacements for hundreds of manufacturers’ igniters.

Why would I upgrade to a nitride igniter?

• The newer Silicon Nitride Igniters are more durable and are harder to break.
• They are easy to recognize by their smooth non-porous surface.
• They also use less energy to operate then older original igniters and they will normally outlast the older style igniters by 2 -7 times.

These replacement igniters cost more but they will outlast the original igniters

For easy installation some nitride upgraded igniters offer retrofit kits, including multiple brackets to fit the mount in the current furnace. Manufactures such as Honeywell, White Rodgers and TrueStart offer retrofit igniter kits.

Always refer to igniter manufactures cross reference before retrofitting. In some cases the Nitride igniter may not work for instance, in a furnace that doesn’t utilize a flame sensor.

There are SIGNS that the motor is about to die:

- Is there a loud grinding noise upon the start of your furnace?

- Is there a continuous grinding noise when the furnace is on?

- Is there water leaking out of the inducer motor?

If you answered yes to any of these furnace motor questions, you should probably buy a replacement ventor motor before your current one breaks and leaves you without heat in Canada.

Your heating technician should be able to catch this potential break down, when doing a furnace service if you are still uncertain if you need a new furnace motor.

If your heating technician did not supply you with a replacement part number for your fasco, GE, AO Smith, Jakel or ICP motor, we will be more than happy to help you with finding the right replacement motor for your furnace in Canada.

CLICK HERE FOR FULL LIST OF CAPACITORS  

At www.heatingpartscanada.ca we sell run capacitors for furnace motors and Central AC units.

A motor capacitor,such as a start capacitor or run capacitor (including a dual run capacitor) is an electrical capacitor that alters the current to one or more windings of a single phase AC induction motor to create a rotating magnetic field.

There are two common types of motor capacitors, run capacitors and start capacitors. The units of capacitance are labeled in microfarads (µF or uF or "mfd" or "MFD", which still refers to "micro", not "milli").

Motor capacitors are used with air conditioners, hot tub/jacuzzi spa pumps, or forced air heat furnaces A "dual run capacitor" is used in some air conditioner compressor units, to boost both the fan and compressor motors

Your AC capacitor is a dual capacitor with 2 uf ratings. One rating for the motor and one for the compressor. The additional connector on top of your capacitor is the neutral.

When buying a capacitor in Canada, call our office to help 1 844 73PARTS. The quickest way to find your replacement capacitor is to read the mf rating right from the old capacitor.

Most common dual AC capacitors with work in most central air conditioners like Lennox, York, Carrier, Coleman, Keeprite, Ruud, Rheem, ICP, Comfortmaker, ArcoAire, Ducane and Trane are as follows:

30+5 capacitors, 35+5 run capacitors, 25+5 dual capacitors, 45+5uf

To buy a replacment capacitor in Canada, we have two pick up locations for capacitors in Mississauga ON and St. Catharines ON. We also ship to all Canadian locations. We sell capacitors to home owners as well as contractors in Canada.

3uf 4uf 5uf 10uf 15uf 20uf 25uf 30uf 35uf 40uf 50uf 55uf

15/3mfd 20/3mfd 20/5mfd 25/5mfd 30/5mfd 40/5mfd

Run capacitors are designed for continuous duty while the motor is powered, which is why electrolytic capacitors are avoided, and low-loss polymer capacitors are used instead.

Run capacitors are mostly polypropylene film capacitors and are designed for continuous duty, and they are energized the entire time the motor is running.

Run capacitors are rated in a range of 1.5 to 100 microfarads (µF or mfd), with voltage classifications of 370 V or 440 V

If a wrong capacitance value is installed, it will cause an uneven magnetic field which causes the rotor to hesistate at those spots that are uneven, which can be observed as uneven motor rotation speed, especially under load. This hesitation can cause the motor to become noisy, increase energy consumption, cause performance to drop, and cause the motor to overheat

A dual "run capacitor" supports two electric motors, such as in large air conditioner or heat pump units, with both a fan motor and a compressor motor. It saves space by combining two physical capacitors into one case.

The dual capacitor has 3 terminals labeled "C", "FAN", and "HERM", which stand for the Common, Fan, and HERMetically sealed compressor.

Dual capacitors come in a variety of sizes, depending on the capacitance (µF), such as 40 plus 5 µF, and also the voltage.

A 440 volt capacitor can be used in place of a 370 volt, but not a 370 in place of a 440 volt.

The capacitance must stay the same within 5% of its original value.

Round cylinder-shaped dual run capacitors are commonly used for air conditioning to help in the starting of the compressor and the condenser fan motor.

An oval dual run capacitor could be used instead of a round capacitor, but the mounting strap should be changed to better fit the oval shape.

Your furnace heating starts when the thermostat senses that the room temperature is below the temperature you required/set. Most homes in Canada have a thermostat set at 70 degrees / 22 celcius.

The first step is for the furnace inducer motor to pull air through the unit starting the required combustion airflow. When proper airflow is established, the gas valve opens releasing the gas flow through the burners where it is then ignited by a spark / glowing heat from the ignitor or in the case of older units, the small flame from the constantly lit standing pilot.

Next, the unit senses the flame is lit, the spark or ignitor is then turned off. Normally, the gas will burn for a couple minutes before the blower is started to prevent cold air blowing out the vents at the start.

Once the required temperature is reached, the blower motor is energized and air will blow over the heat exchanger. This heats the air that is then supplied to your home through the ductwork and vents.

When the thermostat senses that no more heat is required and the desired temperature is reached, the gas valve is turned and shut off. The blower motor usually runs for another few minutes to cool off the heat exchanger. This can be controlled by either a timer or a temperature switch.
