Thank you Porcupinepuffer,

My original blower motor, 5SME39SL0121 had a stator magnet come unglued (which I have since repaitred). When the motor failed, I sourced another motor of the same part number, but it had that different controller number.

The two controllers are different inside and out but have the same external connection plugs.

The controllers dont seem to have a programmable component as they just seem to consist of large capacitors and rectifiers.

I would share images here but I dont seem to have the option at this time.

I would go on all the job search websites (indeed, workopolis, jobbank,...) and search hvac for your area. Employers will say they are looking for certain requirements, but they are not getting responses that meet those requirements. Employers today are realizing they need to train new hires, so go crazy.

Sounds like it's an ECM. If the replacement one has different part numbers it may not work properly. The actual controller has to be programmed to work with that particular furnace. The speeds may not be correct, or it may not work at all. Have you tried opening your old controller to see if an obvious metal oxide varistor has blown in the circuitry? If so, you can take it to an electronics repair shop and have them replace that part to save money.

Starting January 1, 2026, Ontario is updating the Fire Code to require carbon monoxide (CO) alarms on every storey of a home, including basements, if there is a fuel-burning appliance, fireplace, or attached garage.  Most existing detectors should be replaced every 10 years as well.

Thank you.

I apologize if my question was a bit confusing.

A little background,  the blower motor in my Lennox HVAC quit. The motor setup us 2 part. One is the motor itself and one is the attached controller.

Each have different part numbers. I licated and obtained another motor of the same part number but its ajoining controller has a different controller number.

I realize i can just swap the controllers but i want to learn if the controllers are compatible so i can have extra parts.  Problem is I cannot find any info on the newly obtained controller.

These are GE components.

Were you refering to the part number for the complete Lennox system? Or for the motor?

John

If you have the equipment model number I can tell you what Lennox part number is listed for the blower motor.  There have been alot of revisions and the latest usually includes the motor and ECM module separate now.

Unfortunately those GE numbers won't cross reference to Lennox parts.  Likely the only way to find out is to replace it and see what happens.

I have a GE controller "CB01 0VYS" for a Lennox HVAC system.

I cannot find this number for a parts search.

Can you share a cross reference number or possibly superceded number for my research?

Im trying to determine if this controller will work in place of a "ge ecm 2.3 cp03"

Thanks
John

QuoteToronto, ON, December 5, 2025 — Glen Robinson and Sons Plumbing and Heating (Glen Robinson & Sons) has been fined $10,000, plus a 25% victim surcharge, for safety violations related to a furnace installation under Ontario Regulation 212/01: Gaseous Fuels of the Technical Standards and Safety Act, 2000.

In 2021, Glen Robinson & Sons installed a furnace at a property in Metcalfe, Ontario, but failed to affix the required pressure test tag upon completion. Without this tag, the homeowner could not change propane suppliers. Despite requests, the company refused to return to install the tag.

Technical Standards and Safety Authority (TSSA) also found that Glen Robinson & Sons did not hold a valid TSSA contractor registration at the time of the furnace installation. In Ontario, all contractors working on fuel-burning equipment must be registered with TSSA and renew their registrations annually to continue operating legally. The company's fuels contractor registration had expired for over 10 years and was only reinstated in October 2025.

"Contractors must ensure their TSSA registration is current before carrying out any work on fuel-burning equipment," said Owen Kennedy, Director of Fuels Safety, TSSA. "In Ontario, only contractors with active registration are legally authorized to operate. This registration serves as an essential credential, validating that a business meets the qualifications and safety standards required to perform technical work on fuel equipment."

TSSA's licensees are responsible for renewing their licences or registrations with TSSA to operate legally in Ontario. Devices, facilities, contractors, and businesses regulated by TSSA that operate without a valid licence or registration may pose a risk to public safety. If a regulated party fails to renew or reinstate their authorization, TSSA will take regulatory actions, which may include shutting down equipment or pursuing court proceedings for offences.

TSSA's Lapsed Authorization Policy outlines the scope of lapsed authorizations, licensee responsibilities, and the process for reinstatement. For more information, please visit: TSSA's website.

QuoteToronto, ON, November 10, 2025 — Oasis Pool and Landscaping was found guilty of eight offences related to pipeline strikes under Ontario Regulation 210/01 (Oil and Gas Pipeline Systems) of the Technical Standards and Safety Act, 2000. The Ontario Court of Justice has imposed a fine of $80,000, plus a 25% victim surcharge.

The safety violations occurred in June and July 2024, when Oasis Pool and Landscaping damaged two gas pipelines in two separate incidents in North York, Ontario, causing a loss of gas service to over 50 households in the surrounding neighbourhoods.

An investigation by the Technical Standards and Safety Authority (TSSA) found that Oasis Pool and Landscaping failed to supervise its employee and did not follow safety procedures during excavation work. The company did not hand-dig within one metre of a gas pipeline as required and struck the line, in both incidents, with an excavator. Following each of the strikes, an employee of the contractor sealed the damaged gas line and continued working without reporting the incident—an unsafe and unlawful action that posed a serious risk to public safety.

In the July incident, the company conducted additional excavation without referencing the obtained locates, increasing the risk of a pipeline strike.

According to TSSA's latest Public Safety Report, pipeline strikes account for over 60% of reported fuel-related incidents in fiscal year 2025. These incidents can result in gas leaks, fires, explosions, property damage, injuries, or fatalities. Repairs often require gas shut-offs, leaving nearby homes and businesses without service.

"This prosecution marks the third conviction for gas pipeline damage in Ontario this year," said Owen Kennedy, Director of Fuels Safety at TSSA. "In this case, the company involved even failed to use the obtained locates in one of the incidents. Digging without knowing the location of buried utilities is irresponsible, as it significantly increases the risk of damaging gas pipelines and other underground infrastructure."

Mr. Kennedy added, "TSSA reminds all contractors to follow the rules when carrying out work that may contact gas pipelines. Every contractor has a duty to ensure locates are completed before excavation begins and to dig safely in accordance with safety codes."

Before starting any digging project, both homeowners and contractors must contact Ontario One Call to identify the location of underground utilities such as gas, hydro, cable, and telephone lines. Taking this step is critical to preventing damage to pipelines and other buried infrastructure.

To help protect underground utilities, contractors are also required to follow the safety standards as outlined in the Canadian Standards Association's Damage Prevention for the Protection of Underground Infrastructure safety code (CSA Z247-15).

If a gas line is damaged or a leak is suspected, it must be reported immediately to TSSA at 1-877-682-8772.

Thanks for the advice. I'm open to any kind of work to get started.

I've already walked to all the HVAC places I could find on Google Maps and dropped off over 20 resumes, but today I only managed to leave one, four of the others weren't even at the listed addresses.

Small companies are really hard to find: many don't have websites, some are registered to home addresses, and a lot of Google Maps info is unreliable. I've also given my resume to my instructors, but there's still no news, and the listings on Indeed aren't updated either.

Everyone says walk-ins help, but honestly, I feel pretty defeated.
