If the drain line from the ac unit is tied into the sink drain line, the trap leaving the ac unit has probably run dry. Fill the trap at the ac unit with a cup of water and it should stop the noise. Assuming a proper install, kinda hard guessing about it from here without seeing it.
The gas making the popping noise is hydrogen.
If by "popping noise" you mean backfire, it could be crossed ignition wires, or some sort of misfire.
Rice Krispies IHTH :)
Maybe a stone stuck in the tire tread.
Just grease the fittings... It makes all the difference
Your central air conditioner may make a loud noise when it comes on. This is because it may have a leak somewhere in the system.
i have a jonway 49 cc scooter. it has been bored out but i dont know how much. but whenever i go down hill or reach 60km/hr it makes a popping noise like is is backfireing
The clunk is probably a universal going bad, and the popping out is probably caused by worn sifter bushings
could be a contant velocity joint
Replace the speakers. Adjust the Fade/Balance and listen to find which speaker is popping. The popping noise is most likely from a broken cone in the speaker
central airconditioner makes a clicking noise when running? any idea what to check?
you probably need a cv joint
