That sucker was damn near empty before you juiced it up. Problem after Problem....makes for a long day....expensive bill and a customer who gets shell shocked at the repair costs. Nice job Rick, as always
Great video Rick always enjoy watching the way you get through the madness that we go through on a daily basis. You’ve help me with the way I troubleshoot to basic stuff. Keep up the good work!!!!
By building head pressure I was checking to see if the problem was only because it was 18 deg out or if there was other issues. I like to double check different things to verify my path of diagnoses.
Great videos Thank you for them! I often go on calls where I start to find problem after problem to the point that I question and second guess myself that there is no way all of these problems exist all at once and the unit was running yesterday or a few hours ago. I fear presenting the customer with a quote or the diag and them thinking I am trying to rip them off. Only thing I can do is be honest, fair and hope for the best. Is it just me or is this a thing?
No, I feel the same way, that's the nice thing about recording it, they can see it firsthand. Sometimes I'll present it like, "you're not going to believe what else I found"
As long as your being honest n straight with the customer don't feel bad about telling them what's wrong. Wer the guys that r here to help them n they sometimes need to b reminded of that regardless of price. Stay strong 💪
Typical refer call, nice video. Your right, those timeclocks cost more for a lower quality. Heatcraft typically doesn't install a divider between the condenser fans. No problem if both run, but hard to run only one with fan cycle switch. Air takes path of least resistance through off fan. That condition can also get off fan spinning backwards before switch goes to turn it on again, not good for motor. Over years fabricated a divider between fans, works much better, just not as good as head master.

Good afternoon in Europe we have commercial condensing units from Daikin that units is utilizing R410A as primary refrigerant instead of R448A or R449A and is full inverter because the way of thinking is like Daikin VRV. Those systems it takes much smaller piping and match lower quantity of refrigerant on the cycle. I was curious how is designed this thing and one day when i was on PM on those units i was doing some discovery of the cycle it have head master control and fan cycle control via VFD and master compressor with VFD (Daikin VFD like this on VRV's)
I haven't worked on a walk in that uses 410a, only climate cooling. The GWP is the reason for the new refrigerant. 🙄 404a has a GWP 3943, 448a has 1273, 410a has 1924.
@@HVACRSurvival here in Europe with the AR4 the R404A have 3922 the R410A 2088 and R448A 1387 if the refrigerant is not flammable is allowed up to 40 kW (38-37 kw) if the system is larger is mandatory to use A2L refrigerants. The R410A in commercial Refrigeration systems have a lot more Kj/kg but is "restricted" from companies only Daikin have designed systems for R410A on the commercial Refrigeration side. The Daikin zeas is more like a Refrigeration rack with built in condenser and VFD for the compressor and the fan than a condensing unit for just one individual walk-in cooler.
I have replaced a pile of headmaster valves so far this winter...hear in Central Minnesota it gets cold! That discharge service valve cap is loose on a majority of new heatcraft condensing units i install i make sure to check them on start up. Great video!
Nice video Rick, I worknon this stuff a lot times, seems it's always the same culprits. Been seeing headmaster going out lately across many different guys channels. Maybe quality controls isn't what it used to be.
@@HVACRSurvival They have gone up tremendously in price just in the last 6 months. I don't think that there is any of those out there any less than $700. I do residential new construction and want something to help me find registers covered by sheetrock and the way yours showed up on the condenser it should definitely pick up through sheetrock.
Im not a fan of Those clock I would rather see a digital defrost like the keta therm . What do you think? Nice video love the the thermo image cam. Thanks for the video
If there's not enough refrigerant the coil won't get down to temperature so it just runs and runs and runs and never defrost. The thermostat senses coil temperature of about 18° to shut off then has a constant cut in of about 38°. If there's not enough refrigerant it won't hit that number to shut off temp and defrost.
Customers Choice Give the Customer the Option of to do or not to do & If Customer Refuses Your Recommendations make sure Customer Signs the Paperwork that they Refused that Part of the Suggested Repair at that time & date also they should Build Some Kind of Removable HOOD to Cover that equipment Protect it from the Snow
Nice little run of problems there. Dumping 7 or 8 pounds into that & having so little liquid in the receiver after. She must have been off because the HP switch never saw its threshold. What do you think of some leaklock on that leaking cap? Slow it down.
Good ol' multiple offender! What temperature were they keeping the beer at that they need the electric defrost? Or is that just preferred in your area over air defrost? Thanks for the video Rick, stay safe out there!

the test spray bubbles on receiver was possibly it separating and boiling off, from warm receiver, cold air and fans causing very nasty wind chill.
Good find on the reciever and head master. Those headmasters always go bad in the winter time. Great channel. Im retired now but your a great tech.

Hi I have a question when a system is low on Freon ? Why inside evaporator start building a ice ?
I work on air conditioning and refrigeration both. Which type of evaporator are we talking about? A cooler, freezer, a reach in, what?
@@HVACRSurvival reach in cooler
If there's not enough refrigerant the coil won't get down to temperature so it just runs and runs and runs and never defrost. The thermostat senses coil temperature of about 18° to shut off then has a constant cut in of about 38°. If there's not enough refrigerant it won't hit that number to shut off temp and defrost.
Are you going to remove that rusty suction drier as well?
Yeah I have to take all the refrigerant out anyway. I probably won't replace it just the liquid dryer.

Good ol' multiple offender! What temperature were they keeping the beer at that they need the electric defrost? Or is that just preferred in your area over air defrost? Thanks for the video Rick, stay safe out there!
I believe 30*. Not everyone has electric defrost like this but in my area they like to brag about having the coldest beer.
@@HVACRSurvival Gotcha, makes sense. It probably also helps to keep it colder on the walk-in when they cool the beer lines from the air in the walk-in
cold beer sells, warm beer sends/guides to the other place with colder beer.
