Take a look at this YouTube page that explains with good videos what are some of the common problems with heat pump noise. The one that seems dominant is the defrost cycle a heat pump goes thru when it melts ice off the evaporative coils. In defrost cycle, The compressor runs but the cooling fan does not, so you will hear a loud buzzing sound and the unit sounds like it is stalled...because only the compressor is running to generate heat to melt coil ice.

2008 Ford Taurus, clicking noise that lasts about 15 seconds when turn on A/C or heat.

There may be something in the blower motor, that has either fallen into the defrost duct, or your fan may be going out. Remove the cab filter or remove the fan cover and investigate.

New fuel pump in 01 blazer making humming noise

No Fuel Pumps do Humbbbb, and some loudly, although you probably left the rubber/insulator for noise absorbtion off the pump. The new ones usually dont come with this, unless you get the whole assembley. It's just a rubber piece that wraps around the pump motor nicely and ablorbs that Hummbbbb.. Time to drop the tank again. I hate when I do that..

Noise when steering

your question is pretty broad, what sort of noise can tell us allot about what the problem can be. If it's a whining type noise it's more than likely something to do with the power steering. either the fluid is low ir the pump isn't working, it could also be a bad rack and pinion. If it's a clunking type noise it could be shocks, struts, ball joint, etc etc. If it's a grinding type noise it could be bearings or brakes. It's really hard to say with little to no information of the problem

Heaps of frost/ice in freezer: Whirlpool wro34uw

You probably need to fully defrost the freezer. Switch it off for at least 24 hours and collect the water as it defrosts. Do not try to scrape it as it can damage the product. The cracking and poping noises are most likely the product trying to auto defrost. It is probably too iced up for Auto defrost to work which is why you need to fully defrost. Good luck.

Ambiance 16 seer unit frozen

This sounds like a heat pump. If so, it sounds that the unit is not staying in the defrost mode. Heat pumps have a temp sensor so when the outdoor unit goes into a defrost mode, this temp sensor takes it out of the defrost mode when the temp reaches a set point to ensure there is no more frost. Usually about 51 degrees as a general rule. I would start there.

I have a 10 SEER heat pump about 16 years old, yesterday I notice that the outside unit was making a loud click noise in the heating mode. It's very close to the defrost electrical curcuit board. The unit...

Depending on make and model sounds like a check valve clicking. It can sound like it is coming from that area. You say your unit is 16 years old. Honeywell did servey on unit 10 years and older and found out they loose 25% effeicency after 10 years. You may think about changing it out. With the new tax credits you can get a 16 seer unit for the price of a 13 seer. I went from a 10 to 15 seer and my power bill dropped 40%. Rus.

New 14 seer split ruud heat pump makes very loud knocking noise

Well you may want to have a tech come out and check the freon level, but mostly when going into defrost, some units make alot of noise, the freon is reversed in the unit by way of the reversing valve, it makes a whooshing sound like freon is draining off, as far as the knocking noise, could be as I said in the beginning, might be low on freon, but it could be that, this particular unit does this, I have had units make some really strange noises in the past but functioned perfectly, hope this helped, please let us know, thanks again,

Maytag refrigerator clicking noise and stopped working

How long a period of time have you noticed this noise? If it just started and the refrigerator just stopped it could have entered its defrost cycle. When the defrost heaters come on you may hear the heat causing some expansion. After a few minutes(18-22) the defrost cycle ends and the refrigerator will restart.
