LifeBreath HRV/ERV Replacement Parts

LifeBreath HRV/ERV replacement parts keep heat recovery and energy recovery ventilators moving fresh air at rated airflow after the core, motor, or filters wear down. These units exchange stale indoor air for outdoor air while transferring heat, and in ERV models moisture, between the two airstreams, so a clogged filter or a tired blower motor shows up quickly as reduced airflow or higher indoor humidity. Homeowners and property managers typically notice a problem through a stuffy house, condensation on windows, or an error light on the wall control before a technician ever gets a service call. Because LifeBreath builds several core and cabinet configurations across its residential and light commercial lines, confirming the exact model number before ordering a core, motor, or control board prevents a mismatched part from arriving on-site. Keeping common wear parts on the truck lets a maintenance visit turn into a same-day repair instead of a return trip.

Subcategories

• Core Filters: Filters trap dust and debris before air reaches the heat or energy recovery core, and they need regular replacement to keep airflow and exchange efficiency from dropping off. A clogged filter is the most common cause of a service call on an otherwise healthy unit. Filters are sized to the specific cabinet and are not interchangeable across model families.
• Blower Motors & Wheels: The supply and exhaust blowers move air through the core and ductwork, and a failing motor or a cracked wheel reduces airflow even with clean filters. Techs often diagnose this by checking motor amperage against the unit's rating plate. Motor and wheel assemblies are matched as a set to keep balance and airflow within spec.
• Control Boards & Timers: Control boards run the ventilator's speed settings, defrost cycle, and any wall-mounted timer or humidistat interface. A failed board can leave a unit stuck on one speed or unresponsive to the wall control entirely. Boards vary between HRV and ERV models because ERV units also manage the moisture transfer function.
• Energy/Heat Recovery Cores: The core is where incoming and outgoing air streams exchange heat, and in ERV units, moisture, without mixing directly. Cores can crack or become blocked with debris over years of use, cutting exchange efficiency and airflow. Replacement cores must match the unit's core type, since heat recovery and energy recovery cores are built differently and are not interchangeable.

Buying Guide

Confirm the exact LifeBreath model number from the unit's rating plate before ordering any part, since core size, motor specification, and control board wiring all vary across the residential and light commercial lineup. A part that looks similar from a different model line often will not fit the cabinet or match the wiring harness.

Next, isolate which system is actually causing the complaint. Reduced airflow with clean filters usually points to a blower motor or wheel, while condensation or humidity complaints on an ERV point toward the core itself. A unit stuck on one speed or unresponsive to the wall control usually traces back to the control board or the timer interface.

HRV/ERV replacement parts break down into filters, blower assemblies, control boards, and cores, and most no-airflow service calls start with the filter before moving further into the unit. Checking the simplest, cheapest part first saves a trip back to the truck for a part that was not actually needed.

Pay attention to whether the unit is an HRV or an ERV, since the core design differs between the two and a heat recovery core will not manage the moisture transfer an energy recovery system depends on. Ordering the wrong core type will not resolve a humidity complaint even if it fits the cabinet.

Stocking filters and the blower assemblies common to the LifeBreath models installed most often in a service area covers the majority of maintenance calls, while cores and control boards can typically be special-ordered once a technician confirms the failure on-site.

Frequently Asked Questions

How often should LifeBreath filters be replaced?

Filters should be checked every few months and replaced whenever they show visible buildup, since a dirty filter is the leading cause of reduced airflow on an otherwise working unit. Homes with pets or higher dust loads may need more frequent changes.

Can an HRV core be swapped in for an ERV core?

No. Heat recovery cores only transfer heat, while energy recovery cores also transfer moisture between airstreams. Installing the wrong core type will not resolve humidity issues and can leave the system out of spec for the model.

What causes a LifeBreath unit to run on only one speed?

A stuck speed setting usually points to a control board or wall timer issue rather than the blower motor itself, since the motor still receives power but is not getting the correct speed signal.

Do all LifeBreath models use the same blower motor?

No. Motor and wheel assemblies are matched to the specific model's airflow rating and cabinet size, so parts are not interchangeable across the full LifeBreath lineup without confirming the exact model number first.

What is the first thing to check when a customer reports reduced fresh air in the house?

Check the filters first, since a clogged filter accounts for the majority of airflow complaints. If filters are clean, move on to checking blower motor amperage and then the core for blockage or damage.
