    I've been doing this for about about 20 years or more and I always add to returns to the big 90s like that. That dirty coil also could have contributed to that bad exchanger. But I would have never probably caught that without breaking it down myself because it had a rich nice blue and white Flame. In my experience over the years usually when that boy cracks I get some orange in the flame. Thanks for the tips I'll add this in my notes of troubleshooting. Love your content you do an awesome job peace and blessings😂

      My furnace stays running nonstop but blows no heat. You can feel the warmth by the vent but no warm air blows. I had two servicemen come but they only offer me to buy a new furnace from them. So far no repair yet. I hope its okay for the next 2 months. Damn they say board is bad $600+, fan motor bad $1000+ and need a new thermostat cuz mine has mercury., and a new furnace will run $4200+++ not including yearly service cleaning. I like to just get it repair but not having to buy a whole new furnace when not necessary... Is there any honest repairman out there???

The garage heaters a lot different it's one of those ceiling hung units. I changed the limit switch thinking that was the issue. It's not. I'm going to run some tests and check out the coil but this thing just keeps on shutting off on me. I was also going to try and change the thermostat. This thing was working fine and then it just started shutting off after 5 minutes of operation.

    Thank for the video. I had my furnace replaced 3 years ago and it was oversized. It countinued to over heat and shut off and turn back on right away. Ive had the technician out 7x now though out the install to try to fix. I was told by a different hvac tech that the has was tuned down to temporarily fix the over heating. Well now its in the negative cold snap here in Chicago and my heat cant keep up with the -10s and 20+degree windshield. Runs all night for few days stright sometimes dosent shut off. We went to bed and it was 74 degrees woke up and it was reading 68 degrees in the home. Had to buy a space heater to make it though last few days. Different techs who came out said the furnace installed was to large for my home. Also the return air duck was to small. They said the downstairs area could use a return because it dosen't have one. My question is, is this issue fixable and is the contract responsible for rectifying this problem with the correct size furnace. I have a warranty company that i use and they now said they aren't going to replace it, even though they admited to the contractor they used said the new units to big. My old furnace never had that problem before. Any recourse you can recommend be greatly appreciated.

    Hey, if the return was too small then that could definitely have contributed to the short cycling of the heater and a cracked heat exchanger over time. Evap coil could have been dirty too. Good pointers. It's always my last measurement static pressure and too often I wish I would have went straight to it. That man needs a new unit. Good find.

  • @brunoshvac2578
    @brunoshvac2578 11 месяцев назад +5

    The thermistor was getting hotter then the rating on the limit because it was possibly sticking in to far. That furnace as most Carrier brands use a baffle to direct the air flow directly at the high limit to cool it off. I’d recommend using a piece of tape to hold the thermistor directly on the limit so it sees what the limit does. Nice find on the plugged secondary. Carrier also put out a bulletin for some of there units showing the insulation deteriorating and puffing up inside the primary section of heat exchanger and directly under the high limit the insulation puffs up and blocks a portion of the air from the blower motor even though the baffle is blowing it directly at it, causing nuisance limit trips. Their solution is to remove the limit and cut half-inch strips of metal tape, approximately 4 inches long and put them through the whole of the limit to secure the insulation back to the jacket. No more limit trips. This bulletin is posted and available.Heil is a carrier brand. Great video thanks.

      Hello, do you have some reference material to look at. I am having the same issue. The furnace blower was getting suffocated by the loose insulation above blower motor. The board showed code 33. I removed the loose insulation and still get code 33. I’m planning to replace the limit switch. The gas burners shuts off after couple of minutes. The furnace is about a 4 years old.

  • @ramonconcepcion6083
    @ramonconcepcion6083 6 месяцев назад +2

    There isn't enough dirt to consider that a blocked secondary heat exchanger. The most likely cause is undersized ductwork or oversized furnace. Installing a furnace of the same size will cause the same overheating problem if you don't address the true cause of the overheat problem. You need to include duct static pressure test in your troubleshooting . I do agree with you about needing returns on both side or 1 on the bottom for a 5 ton furnace

    I have a 70k btu furnace and have more return. My furnace ran great for 28 years so I have already replaced all the components. This spring I will pull the heat exchanger and if it is even slightly bad I will shop around a find a new one. New furnaces don't last as long as the old ones. If I can get another 28 years off this one it will be somebody else's problem in the future. This only works if you can do this yourself.

    In this configuration, would it be fair to say that an air flow restriction would begin (excluding the filter ) at the secondary heat exchanger THEN the underside of the “A “ coil ???? If this is true, in cooling mode, the first place to look for a restriction would be just above the blower motor ????

    Instead of taking the front face off of the coil could you check with a camera threw the hole for the high limit or would that ever not be a possibility?

    Good stuff taddy! Idk why after a rough field tech week, your videos are soothing.
    Would you share a stumper/hard call video? Or I'm just a bad tech and you don't have bad days? Thank you for the quality content!

    most homes don't need such large equipment. probably grossly oversized furnace and a/c on undersized duct.

    Is that something you could find by measuring the cfms between supply and return?

    Great video but do you really want to pull air from an unconditioned space ?

    @sauloadolfoescobarescalona5389 8 месяцев назад +1

    I have the opposite issue with a furnace, it triggers the limit switch after a few hours of operation it shutdown. Could it be low blower speed, pressure is good, no returns or filters clogged

    quick question when removing that coil you have remove the refrigerant right? you also have to either cut the line or un-sweat right?

    Would measuring static pressure be worthwhile in this scenario?
