∆ (delta) Test for a Lennox XC21036230 03 Air Conditioner
Where can I find documentation as to where on the Lennox site or elsewhere that I can find this information. It is important to me that my unit was properly tested and set to standard settings or range.
I have looked everywhere on the Lennox site so it must be hidden pretty good. Thanks.

Hi jean, If you haven't found a remote yet then try Ebay OR Amazon..... The link below is an Ebay page showing a few different lennox remote controls, I hope this helps............CHEERS..

Yes, there is a way to test the capacitor. The safest way is to shut the power off and leave it alone for at leas 10 minutes. Then take it out and using an analog ohm meter (with a needle) touch the 2 test leads to the two terminals. The needle should jump, then slowly go back to zero. Reverse the leads and the results should repeat. Do this several times, as the needle may not move the first time. also, check each terminal to the outside case. There should be Infinate resistance from each terminal to the case. If the capacitor is good, there is another problem. If the capacitor is bad, you need to find a lennox part source. Give them the model and serial number of the unit and they will make the correct capacitor appear.
If you are good with a multimeter and amp meter, ask me for a mathmaatical way to calculate the capacitance. It requires building a small test device and use of a calculator.
verymuch so it is clogged up , now open system treat drain pan with bleach ,blow out two lines if there are available but if theres only one treat that on ,then treat the coils clean an treat them after cleaning pour little bleach in the bottom of the pan
Here are a few ways to calculate your BTU's.
Get ready to use that algebra you thought you'd never use.
1 Ton = 12000 BTU's
400cubic feet per minute (CFM) = 1 Ton on standard ac units (300 is an absolute minnimum)
BTU's air heat = difference in temp. ( ∆T ) x 1.08 x CFM ∆T = BTU's / (1.08 x CFM) i.e. 65◦F entering your unit and 93◦F air leaving on a 12000BTU unit. ∆T = 28 CFM = 400 28 x 1.08 x 400 = 12096BTU's Another way... Electric heat calculations. BTU's = KW (killowatts) x 3413 Watts = Volts x Amps (single Phase) Most Homes)) Watts = Volts x Amps x Phase (this is for three phase units.)three wires and a ground)) 120 volts 30 amps single phase (common) 120 x 30.0 x 1 = 3600 or 3.6KW 3.6 x 3413 = 12286BTU's
