One thing also is to check if it really is draining by adding water to the pan and see what happens. Also a trick I use is to suck the water out of a condensate drain with a wet/dry vac vs blowing. ...

There could be several issues happening.. like, low charge, plates seperated, water slowly draining passed dump valve, water float set too low. Are there any cubes a good size?

Freeze damage, like someone said try to get the line to slope out to it's drain so it can't have water in the line next time.

Stage them with 2 tstats and change lead lag after a couple months.

Where is the tube ending up at?.

Wrong oil in a rack. Added POE oil to a R-22 system on a 30 yr old 5 compressor rack...ugggg

The biggest thing with True equipment is the True tstat must match the the coil temp. So use a true cap tube and watch your charge. The tstat drops down to about 20F then warms up to about 40F to...

It can be inside or outside box. Evap coils will need a means of disconnect in any case for code. So a tech can work on unit while the power is turned off.

John here are some things to consider. If you have a used box and used equipment then more than likely is was a good match for you area of the country. LV coils are supposed to be use for high...

For years I found time clock defrost when the clock tells it to go into defrost. Sometimes when it's not needed or not enough times. Low pressure controller goes into off cycle when the coil needs...

Guages and electric meter will tell your problem.

Well on some larger systems the heater won't energize till compressor shuts off. Heater relay off aux contacts on compressor contactor. Your post #13 is a good starting point to check.

Slower blower speed to 350 cfm per ton and check to make sure your condensate it trapped proper, vent after the trap and is draining. Water being held back can also keep the levels up. I also agree...
