Was expansion valve changed ? A bad expansion valve would let liquid refrigerant flood back to the compressor hence the knocking.

Will bad knock sensor stop ignition from sparking?


I'm going way back into my alcohol erased memory on this one, but check your oil level sender. I ran into this problem many years ago and it seems like that was the culprit.

Replace both thermostats. One or the other is sticking, and there is no way to test which one is bad... since test unsticks a stuck thermostat

We have an 11 year old fisher-paykel fridge .For past 6 months several times a day it makes a loud knocking noise


If this noise happens when the compressor turns on and shuts off it is called a compressor knock. All the internal workings of the compressor are supported by springs, over time the springs wear out and become weak. When the compressor stops or starts the tourq causes the internal parts to hit aginst the casing of the compressor. Sounds like a clunk clunk clunk noise. If you can deal with the noise do not go out and replace the compressor cause it will work just fine like that.

I would say control board. Get on Samsung web site and go to technical support and get there 800 number. I have called several times and they can walk you thru it. Just have your m They model number handy. They can also tell you wether you need a service tech or not. Be sure to ask for free estimate. Rus

2001 H-D Road King engine knock


For valve train noise try these:
1. Low oil pressure caused by oil feed pump not functioning
properly or oil passages obstructed.
2. Faulty hydraulic lifter(s).
3. Bent push rod(s).
4. Incorrect push rod length.
5. Rocker arm binding on shaft.
6. Valve sticking in guide.
7. Chain tensioning spring or shoe worn.
8. Cam(s), cam gear(s) or cam bushing(s) worn.
9. Cam timing incorrect.

If it is a bottom end knock, an engine tear down may be in order.
