Why is the Timer LED blinking on my Carrier 38QH36-H Air Conditioner?
If the timer LED is blinking on your Carrier Air Conditioner, it could indicate a faulty return air sensor, a faulty return indoor coil sensor, or a faulty return outdoor coil sensor. Determine the reason and replace the faulty component.
Why is the Power LED blinking on my Carrier 38QH36-H Air Conditioner?
If the power LED is blinking on your Carrier Air Conditioner, it could be due to compressor overheat, anti-overheat protection being active, or low ambient temperature. Determine the reason and correct the issue.
What causes excessive section pressure in a Carrier 38QH36-H?
Excessive section pressure in your Carrier Air Conditioner can be caused by a reversing valve that is stuck or has an internal leak, in which case it should be replaced. Another cause could be an internal pressure relief valve that is open; check for the source and eliminate it. Overcharging the refrigerant can also lead to this issue; purge any excess refrigerant.
What causes low head pressure in a Carrier 38QH36-H Air Conditioner?
Low head pressure in your Carrier Air Conditioner can be due to a low refrigerant charge. In this case, check for leaks, repair them, and recharge the system. A restriction in the liquid tube can also cause this; remove the restriction. Additionally, a dirty indoor section air filter can be the culprit; clear the filter.
