Nice work!

I personally like Aprilaire. I really like the 700A

Make an offer. I want this out of my truck!

Someone make an offer. I want this gone!

The thermistor controls evaporator temp only. The hopper temp is controlled by the EPR valve (evaporator pressure regulator). The is a schrader on the vale along with the rating. I believe it 56-58...

I work on A LOT of Hoshizakis and the hot gas bypass valves do fail.

I would check the start Capacitor as stated.

Have a Tjernlund Inducer Interlock with speed control. Model UCRT 120VAC 6 amp Max. About 1 year old and works perfect and looks like new. Comes with Vacuum Switch and pressure sensing tube. $125.00...

I have a brand new in the box Trane/American Standard Condenser motor.
Specs are:
1/2 HP 208/230 volt 1100 RPM 3.92"x 1/2" shaft, ball bearing 1 phase

Would sell for $125.00 shipped.

No insulation on the accumulator.....bad bad idea;)

Brand new in the box Maxitrol A1010A amplifier. Special ordered and wasnt the issue. Contact me if interested at a.meminger@yahoo.com

and the superheat at the coil (before the subcooler, obviously) was 18 deg, which isnt horrible but from what i remember 12-15 is the norm.


You need about 6-8 deg for a cooler and about 4-6 deg...

That valve is called a head pressure control or a headmaster. The valve has a set pressure and it modulates by bypassing the cond. to maintain head pressure

Have always used 408 without a problem. Pressures are darn close

OH OH and then a coffee break:D

Pull the x wire off the time clock, sounds like you have a bad defrost termination switch. The time clock will not come out of defrost unit the set amount of time is up. If this works then take a...

Sorry my mistake you are correct, the green light will be solid when there is a call for heat. Only flashes when in test mode or heat failure

If i recall the green led light on the heat board needs to be a steady flash when there is a call for heat??????

A new HSI from Trane is approx 46-48 ohms. Tranes spec on resistanve value for a good operating ignitor is from 50-80 ohms. I like to replace them at about the 100ohm mark. I have replaced a ton of...

I agree with you, but now a days its all about cost. A 2 pole contactor is cheaper than a 3 pole is what it all boils down to;)

According to A training class I attended hosted thru Copeland CCHS are hot required on any of there single phase compressors. Three phase scrolls require a CCH if they are over 10LBS and do not have...

I see the grasslins fail quite often. I prefer the basic paragon 8145-20 defrost timer. When the grasslins fail i install the paragon.

I would not wast your time on a piece that old. Get a new shaft, some bearings and a new cage. I would bet that the old cage is out of balance and could have contributed to the bearing failure. If...

Thats funny. Know the feeling

Once the system is triggered the shunt will take out all equipment and the is a gas shut off for all gas equiptment. The exhaust fans should stay running to clear the smoke.

I like to get the gaskets nice and warm under a heatlamp and then install them,. If they still are off a little bit take a heat gun on low and get the high spots warm (be careful not to melt them...

I really like the aprilaire 700A. Have installed many, the outdoor temp sensor and the automatic controller are great and once you get the proper humidity level in the house, there is really no need...

Sorry the controls were sent back to copeland and I dont have the info on them. They were all the same applications and were all new not more than 6 months old. 404-a cans and medium temp

Please explain.

Yes that is correct even though the compressor is air cooled the the compressor still needs a small amount of liquid coming back to cool the windings. Someone please correct me if you feel im...

Please explain a little more on the problem you are having. You say the amp draw is way below the spec. WHats the spec and the actual amp draw???? Under loading the motor is almost as bad as...

Suprised they are still alive

If all three hoods went down at the same time sound like a power surge or a dropped leg to the units. I had a store that had auto resets and the store lost a leg, the 3 phase motors were single...

Sweet truck>>>>>>>

The Danfoss TVX's quality is questionable..... I have had a lot of issues with them. There cold control is also garbage in my opinion..

The temp taken at the compressor will be more than a few degrees higher. A tipical walk-in cooler set up with a copeland recip. requires 6-8 deg of super heat at the evap and 20 deg of superheat at...

Anyone out there ran into a copeland dual pressure control blowing the diaphram on the low side??? I have ran a call on 3 of the the past months and all 3 the diaphram split from the case and blew...

The super heat can be measeure leaving the evaporator or at the compressor. You want to take you pressure reading at the suction line on the evaporator, convert oressure to saturation temp. Measure...
