Minim 20 amp circuit ... is this 110 or 220? You need to know.
20 amp circuit needs to have #12 wire. If 110 Volts, you need a black, white and green #12. If 220 Volts you need a black, a red, and a green. If you have anything IN the unit that needs 110 (probably not), you need black, Red, White and Green (bare) #12 wire. Definitely needs to be on a dedicated circuit. If your unit has a resistance heater (electric) you will need a 30 amp circuit (probably 220) which needs #10 wire minimum. 220 volt breakers are double. You will need two spaces in your panel box. Would not hurt to put in heavier wire (#8) protected by a 30 amp breaker ... $ is the governing factor.
Having said all of that --- you should be reminded that I dont even know what country you are in nor your prevailing voltage nor what your national or local codes require. My comments based on installing several Goodman products over several years on the Eastern Seaboard.
If this is the model number of the unit, it would be a 2 1/2 ton unit. The seer I couldn't tell you with out seeing the manual. Could be a 10, 12, 13, cant tell with this information. Sorry. Shastalaker7 A/C, & Heating Contractor
My books do not go back far enough to get you the Seer rating, it is a 5 ton unit and as the serial number shows it to be a 1999 model, it is probably a 10 SEER unit, maybe a 12 seer, but not likely, but I can tell you that it was manufactured on the 8th week of 1999.
I hope that I have helped, have a great day.
A bad connection in the power wiring, the circuit breaker, disconnect, capacitor(s) or in the compressor contactor (worn contactor) can cause this due to very high resistance and subsequent heat production. If the unit will run, it should be amped checked to trace the cause.
This assumes that the wiring is correct and that the unit was functioning properly before these issues manifested themselves.
Check your filter. Make sure it is clean. Make sure the outdoor unit is operational. (power on). Clean your condenser coil with a garden hose. If possible check your evaporator coil. If it is dirty clean it. Your furnace (or air handler) blower speed should be set on high. All of your registers (supply & return) should be open and unobstructed. Check for proper thermostat settings. If none of this information solves your problem , then your units charge needs to be checked. You could be over or undercharged with freon.
