What are the reasons for the 8th generation Accord's air conditioning not being cool?
2 Answers
8th generation Accord air conditioning not cooling generally has the following reasons: 1. The compressor capacitor is damaged or faulty, causing the compressor not to work. 2. Refrigerant leakage in the air conditioning system: manifests as both the indoor and outdoor units working, the compressor also working, but with no effect. 3. The remote control is faulty or the air conditioning receiver is faulty: manifests as the air conditioning not responding when turned on, or working intermittently. 4. The resistance value of the room temperature sensor changes, causing the outdoor unit not to work. 5. Air conditioning power supply issues. 6. Four-way valve or compressor high and low pressure gas mixing, the air conditioning works but has no effect. 7. Fault in the indoor or outdoor unit control board causing the air conditioning not to cool: manifests as no response when turned on or erratic operation of the air conditioning. 8. Damage to the indoor or outdoor fan, with the outdoor fan damage manifesting as excessive exhaust temperature or high pressure protection, and the indoor fan damage manifesting as frost formation on the indoor unit, the outdoor unit continuously working, and moisture entering the indoor unit.
A friend asked about the 8th-generation Accord's AC not cooling, and I guess it's a common issue. I've driven this model before, and most AC problems are due to refrigerant leaks. Over time, system aging can cause cracked pipe joints or a faulty evaporator. The compressor might also fail—if you hear the fan running but no cold air, it's likely the compressor isn't working. Another possibility is a clogged air filter; if it's packed with dust, it can't blow cool air—try removing and cleaning it yourself. Also, check the electrical components, like burnt relay contacts or faulty sensors, which might prevent the control module from sending signals when the AC is turned on. Don’t overlook simple causes, like an incorrectly set temperature control switch. If the compressor is burnt out, repairs can be expensive, so it’s best to regularly visit a 4S shop to check refrigerant pressure and recharge frequency. Safety first—driving without AC in summer can easily lead to heatstroke, so get it checked early. If a warning light appears on the dashboard, stop immediately—don’t push it. Professional repair shops have tools to detect leaks and apply sealant, saving you money.
