On your thermostat switch the system "off" switch the fan "on" and check for smell. If it still smells, could be fan motor overheating. This may be causing the outdoor problem.

Note: Display only for "- -" (No signal transmission, no receiving sound and no Power LED blinking)
4 Press the TIMER ? or ? button on the remote control. The code "H00" (no abnormality) will be displayed
and signal will be transmit to the main unit.
5 Each press of the button (? or ?) will increase error code
number and transmit error code signal to the main unit.
6 When the latest abnormality code on the main unit and
code transmitted from the remote control are matched,
Power LED will light up for 30 seconds and a "beep" sound
(continuously for 4 seconds) will be heard. If no codes are
matched, Power LED will light up for 0.5 seconds and no
sound will be heard.
7 The breakdown diagnosis mode will be canceled unless
pressing the CHECK button continuously for 5 seconds or
operating the unit for 30 seconds.
8 The LED will be off if the unit is turned off or the RESET
button on the main unit is pressed.

Note:
"O" - Frequency measured and fan speed fixed.
The memory data of error code is erased when the power supply is cut off, or press the Auto Switch until "beep" sound heard following by pressing the "CHECK" button at remote controller.
Although operation forced to stop when abnormality detected, emergency operation is possible for certain errors (refer to Error Codes Table) by using remote controller or Auto Switch at indoor unit. However, the remote controller signal receiving sound is changed from one "beep" to four "beep" sounds.

How can resolved PJ error in daikin vrv 2


PJ is an error that has to do with the outdoor unit not matching the indoor unit. This means the outdoor board thinks it's a 2 ton unit and the indoor thinks it's a 1 ton unit. (Just throwing those numbers in)...but, the indoor is not matching the outdoor. You need to read the manual and go through the setup process.

Not cooling good and has an odd smell.... We've repaired a leak in freon in 2 places in the last 2 months!! ugh!!! I'm so frustrated with this thing.... it was cooling like a dream when we first installed...


Where were the leaks in the system. If they were in either the indoor or outdoor coils, I would replace the entire system. If they were in the refrigerant lines that connect the indoor and outdoor units, I would replace the line set only.

Normally, blinking 5 times means for drain motor malfunctioning. Check drainline, oif blocked clean it. If drain motor not working, replace it.
If blinking 2 times, Indoor room air thermistor defective replace.

Thanks.

Where is the fuse/breaker on a goodman cple 18-1


Hi, I wanted to look up the numbers you gave me as you listed 2 different model numbers, the CPLE-18-1 is a 1&1/2 remote condenser and the other you showed CPLE-24-1 is a 2 ton unit. Doesn't matter, but if your power was lost you have your main breaker box at your meter, and at the condenser you will have a disconnect box with a pull out type plug. If you see no fuses, try removing the plastic cover as they are required to install 2-fuses in side the box also. If this is a split system with the outdoor and indoor unit, you will also have a breaker inside for the indoor unit, its high voltage and you will have a circuit board in the indoor unit with a 3 to 5 amp auto type plug in fuse.
I hope this has helped you out on this. I will be here if you have more questions. Please do not forget to rate me as I know you will be kind. Keep me posted.
Sincerely,

U4 System transmission between indoor and outdoor units Daikin


Sounds like an interconnecting wiring error. Check wiring connection i.e. wires are connected in right order 1 to1 2 to 2 etc. from indoor terminal board to outdoor terminal board. Also check for slack or loose connections.
Hope this helps I take the time to answer your question so please rate me
