I appreciate your vids like this, because when I run into reefer calls at school, I like to have an insight on your troubleshooting skills. I know your pimpin' out the DL429, and when asked, I tell folks for $200, she's the best piece out there!
Got to love the freezer. everything is off but that box still cold as hell. your buggies freeze up lol. lucky you that drain pipe wasn't that long. good stuff
Great job I'm a residential Hvac guy and Ive always wanted to do refrigeration just not many opportunities around my area to learn it real well but I learn something new every time I watch your vids please keep them coming
Ice on a freezer evap always turns into a big job , especially when the drain blocks up ..... Would be cool to watch you do an oil change on a compressor one day ☺
I've been ignoring an ice buildup on the floor of of a large WI freezer at the track, but its starting to resemble an ice skating rink in there. Copper drain line split somewhere...time to get the coat and gloves, there is a LOT of product in there!
Hi Dave.first i must say that i started watching your videos about six months ago in ac class... three months later i got my first job in refrigeration.. and today i had a drain line heater kick my ass during a service call. Keep putting out videos. You are inspiring a whole new wave of techs! Quick question though, map gas wont damage any of the housing for the evap coil or the coil itself? Seems WAY more productive than using a pump sprayer filled with hot water
One thing I've seen in the past, is to make a metal tab (usually from aluminum sheet metal or a strip of copper) that wraps around the drain pan heater and sticks down into the drain nipple to transfer the heat from the drain pan heater into the pan nipple to keep it clear.
Hey Dave any tricks for like when you are replacing a txv or old compressor to get out any trapped Freon on out so you don’t the killer gas ? I did purge with nitrogen and did a vacuum what’s the best way thx
My experience is that cable ties, especially the white ones, tend to stiffen up and crack after a few years. You might have been better off using some copper wire to hold it up. However, done is done, and that should certianly last a few years.
That crappy drain freezing up was more likely due to air being sucked in through the open connection than from heat transfer. Also, that Dunham-Bush ECLS-65 evap was designed as a draw-through coil, not a blow-through. I'll bet dollars to donuts the installer screwed up and had to change the fan blade.
It's in line with total amps when combined with the other heater in the coil. Total amps 7.5. I'm around 8. The heater could be weak it's old as the hills.
Thats a Very difficult one to diagnose But, i think u Nailed it ! i don't like those Heating Element Connections. does not look,like a good connection method. kinda funky. Wow, an Old 1981 Dun & bush. Evap ! Thats the Oldddd Time Quality ! Those old freezer evpas seem to last good from that era. i've got avid up of that one i rebuit with that old flare nut city on that expansion valve.

That meter is great. I like it. I'm over a year with no hiccups.
+Nor-Cal Refrigeration & H.V.A.C loving the meter as well. Great for the price! Lol
+Rob HVAC lol

Thanks Derrick.
Nice Video! You do great work and even cleaned up the freezer for them lol. Have a great Labor Day Dave! Thanks for sharing.
Have a great Labor Day also.

Go to heavy diesel channel lots of oil changes there. Good stuff
that went quick, glad you didn't have to thaw that evap coil!
Great Work Dave

Hmmm ... one of those "could be any or a combination of multiple" situations. Gotta luv living with uncertainty
nice scenery by the way!

Refrigeration Technology you have to be real careful using map gas it will melt everything and you need good ventilation too. Be careful 👍
Nor-Cal Refrigeration & H.V.A.C in other words ill just stick to my hot water pump. Not trying to be in hot water with the boss. Respect for the reply
Thank you for nice video. Love the meter don't know why its so underrated
Hvac Apprentice the UEIDL429 is HVAC standard equipment revived very well by HVAC techs.
That is a wierd drain line connection. That strap is genuis!
It's all I had. I use the plastic plumbers strap but I was out.
+Nor-Cal Refrigeration & H.V.A.C I just added that to my tool box. I've never thought of that before. Great idea!

Yo le pondria tubo pvc
Okay 🐊 alligator clamps 🗜 got it for the fith time lmao
Great video ! Interesting how the blower is reversed.
If we use ppr pipe for drain line.were i can install the wire heater
sweeeet video!!!!!!

Yep. The whole box was used and the panels are shot. It's on the slate for replacement next June
What kind of ohms are you looking for on that drain pan heater?
Familia Sanchez HVAC volts divided by amps equals resistance. Bam 💥
Kind off odd to see the evap fans on the other side. Haven't seen that before
1 st. For me as well.
That's a small WI but I haven't seen that either. Interesting!
KrackHead Refrigeration installing since 1981.
+HVAC/R Junky yep
Bro how many amps taking drain heater
Ice Ice baby!!
Lol
I'm going to be changing one out tomorrow. I don't really work on walk in freezers, how long does it usually take to change out?
Depends on how much ice you have to melt and access to evap coil.
.9Amps seems a little to low to me. That is around 200watts. Nice vid.
It's in line with total amps when combined with the other heater in the coil. Total amps 7.5. I'm around 8. The heater could be weak it's old as the hills.
What terminals do this heater goes to ?
Hackin and mowin
hi what is normal ohmage on drain line heater?
The one on the drain ?

I saw that video. That was crazy. The old stuff was so good our industry was solid back then.
