Error 72 after diagnosis

Code 72 usually has to do with start components. Either run or start capacitor could be bad, or start relay could be bad.

Depending on how cold it is wherever the vents are located if they're underneath the crawl space or something it's possibly colder down there so in order for it to become 72 in your house it's going to have to determine how much it's going to take to put 72 in your home if it was burning at 72 and pushed it through cold vent piping it's not going to be 72 when it comes out your vent I believe this is normal hot air will not melt or catch linoleum on fire also check to make sure your vents are all clear of debris dust lint and things like that I wouldn't mess with your furnace adjustments you could be opening up a can of worms especially this time of year now if it starts to smell like fuel or it's sporadic then I would call a repairman

timed cycle mean dryer not on sensor dry mode. check wire connection on moisture sensor bars (i think you forget to put 2 wire connector put together). when you use other cycle dryer use moisture sensor to dry cloths so sensor not working dryer will stop in 5 minutes or so because dryer think there are no wet cloths to dry. hope this help you.

Error code = Operation light x 5, Timer light x 2:
IPM protection
Abnormal current value of IPM is detected.
> Permanent stop.
[Diagnosis Point]
- Heat radiation is blocked (inlet/outlet). - check indoor and outdoor coils for blockage by dirt. If outdoor blocked, turn off power and gently hose down coils from top to bottom (that's the radiator like assembly). Don't spray upwards as you can force water onto circuit boards. Allow to dry and turn power back on to check.
- Check if outdoor fan is defective (does not rotate).
- Controller PCB defective (Refer to after mentioned "IPM diagnosis").
- Refrigeration cycle defective (Refer to after mentioned "refrigeration cycle diagnosis").

This normally ends up being a faulty controller board but there are quite a few tests that you will need to do to make sure that no other parts are causing the error. It's best to get a tech in for this one.

Sounds like either a short between the G and R t stat wires or the relay in the control board is faulty. Easy way to check is remove the G wire from G terminal on the control board, if the blower stops, there is a short in tje t-stat wiring, if it continues to run a new control board will be needed since the relay is part of the board.

my mini get air light on code 72.

sounds like it ,could be the clima computer ,

Possibly the thermostat?

if you have a whirlpool/ kenmore dishwasher and the clean light is flashing 7 times then pauses and then repeats, it is a problem with the heating circuit.
follow this keypad operation: push the high temp wash, air dry, high temp wash, air dry. this will put the unit into a service mode and it will run a short diagnosis cycle. after it gets done, about 5-7 minutes, then it will reset and allow you to use the unit again.
make sure the water is hot enough at your faucet at least 120 degrees, and the door is getting closed tight.
