You’re always measuring the contactor coil resistance, but the coil itself seems highly unlikely to fail. What about the resistance of the contacts themselves? Would seem that the high current-carrying contacts are the wear item. Not the coil.
Not necessarily true. High coil resistance is a sign the contactor Is on its last leg. The higher the resistance, the less magnetic pull is available for the contact points. There by causing the points to arc more and burn is not a positive lock in..
@@marcinmerrimack1726 As the Pipe. Dr has said wear a tear. But if I might add to Pipe Dr reply worse enemy is HEAT!!! Heat will cause tempering of the copper wire molecules and that will also raise resistance which also increases the ohms. Lol I could explain the whole process but would be too long to explain in full detail. But the nuts and bolts of it is ::: as the contactor wears with time an “heat” it increases the ohms resistance their by weakening the magnetic field to pull the contact switch together. Instead of a positive snap in? It will be a lazy slow an weak connection and that causes the contact points inside to heat an burn resulting in -A stuck contact either froze in open or stuck in closed an B that is bad bad news for the compressor. That is why he always checks the resistance . An ounce of prevention is worth a pound of cure $,$$$.00 Trust me their isn’t anything worse to a customer than having to call us back 3 to 5 days later.Pipe Dr knows this well from experience as I do 😉( edited fur a spell boo boo) Hope no offense is taken Boss for adding to your reply ❤️
some newly built houses in florida are built with basements, i mean i grew up in florida but since have moved back to my birth state and if i was building a new house of my own anywhere in the world i’d probably want a basement! I don’t like crawl spaces, but having a basement to finish and then a first and second floor why not bring the home feeling with me 😂
Those lennox units are notorious for being mouse or squirrel nests. Plainview has TONS of them
Yup 👍
Good vid Mikey ... Thx for all you do
I appreciate it!
Hey Mikey Pipes, nice video! Concise and informative. Good job.
Glad you liked it!
Bring Bosch to Florida Mikey!
Slow and steady
Nice job as always Mikey....love me Fridays!!!
Thanks again!
Glad You cleaned up that nasty mess. Some would have left it like it was.
My thoughts exactly
Hey Nice work & tutorial
Mikey Pipes
Those critters can cause some damage.
They surely do
Anytime I run across a faded data sticker; use a UV light to be able to read it. Keep it up brother! God bless!
Awesome idea. I’ll try that
Who would win a MMA fight between Conner vs. Matt ?
Conner
when my 2000 Trane heat pump goes i'll be calling you guy's, it still runs like brand new though
I'm still trippin' everytime i watch your videos Mikey.
Ty
@@MikeyPipesOrlando Ty = Thank you!
Good afternoon Mikey. First time I’m the first like on a post.
Morning!
Watch out for the fire ants in FL as well ,I've changed a few contactors due to those lil bastard's 😂.
The struggle is real...!
It sure is

@kat2641 What could cause the coil resistance to rise over time?
Wear and tear

@@MikeyPipesOrlando And ferrous oxide!
Back when Lennox was well built 😊
Exactly. Now it’s garbage
OMG...I would have worn a full respirator.
It was horrible
Is this Florida? Why is there a basement window?
Humm
Looks like a service call in NY not Florida (Scam)
