Tired of inexperienced repairmen , i did some investigating , here is what i can share:-
When you switch the fridge off always give it at least 15 minutes rest before you turn it on again.
Problem : U left the door open for a while: Now it is not cooling properly.
Humidity has turned to ice and has blocked the cooling system.
Solution Let ur fridge thaw …ie switch it Off and keep the doors open for a day or two and then switch it On again . Be prepared to remove excess water from the back of the fridge ie in the tray above or besides the compressor or the black oval thinge.
Problem : Freezer Frozen Solid , Noisy obstructed fan, Frost free fridge not defrosting
1. Fan : Check if it is working or not. If blocked check 2 and 3.
2. Bimetallic Thermostat: Good if continuity is YES when cold and NO when room temperature : Bad otherwise or if puffy or if not good
3. Heating Coil or heater : Bad if Continuity is broken or if MM reads 1
: Good if Continuity is ok or if MultiMeter reads 0.
Generally a bad thermal fuse with no Continuity could be a sign of bad heating coil, or bad circuit or defrost timer.
If both are ok Problem is more serious and could be the Circuit, Timer or Temperature sensors.
Disconnect 2 and 3 from circuit for 6 to 8 hrs and chk out cooling and frost buildup to isolate whether problem is in 4 or 5.
4. Temperature sensor / Thermistor:
Generally there are thermistors in both sections freezer and fridge.
Faultfinding : Resistance in a thermistor increases as temp drops and vice versa. At room temperature 68°F.,the sensor should read approximately 6.1K Ohms. With the thermistor submerged is a glass full of ice water, the sensor should be very close to 32°F which should read approximately 16.3K Ohms
5. Circuit or Mechanical Defrost timer
The circuit board is damaged or the mechanical timer is stuck .
For mech defrost timers watch :-
How the Fridge cooling System works
Liquid refrigerant (Freon/ R134a) entering the evaporator begins to boil into a gas because of the sudden drop in pressure created by the compressor. This change of state absorbs heat. The temperature inside the evaporator coil may be -20 degrees F. This will condense and freeze moisture in the air in contact with the coil (which is why we have to defrost). If there is freon boiling inside the evaporator this frosting will occur within minutes. So if we run the unit with the cover off the evaporator and no frost forms we can know that there really is no freon or the the system is clogged. If the unit runs for several minutes with the door closed and the freon charge is correct, the frosting should form all along the length of the evaporator.
If the cooling system is good in a top freezer fridge , when the compressor has run for some time and is still running :-
Major Problem : Fridge doesn’t cool properly
1. Could be a choke or a leak in the cooling system,
2. Could be a clogged filter dryer or capillary tube, or worse in the radiator or co
3. Could be a gas leak or low on gas because of age or leakage ..
The fridge has to be regfilled with R134a
Major Problem : Fridge does not start !
Check the Cooling system, for problem with the defrost Circuit board or mechanical defrost timer.

I tried my hand at refilling my old Canon PIXMA iP1800 a part of the 1600/1700 / printer series .HP inkjet cleaning ain’t too different.
Ink Level Monitoring
Disable the ink level monitors after re-filling the cartridges. Go to properties, maintenance, view printer status, option and uncheck enable status monitor.
Fault Finding and Service
Printer Service required : Printer Properties /Maintenance
1. Printer head Alignment : for Misaligned prints.
2. Roller Cleaning : If there are vertical lines on the paper it is the rollers that are the problem. If rollers make a creaking sound oil the roller ends.
3. Smudges : Bottom plate cleaning
1. Cartridge not detected /doesn’t recognize the Ink Cartridge : Ink has dried up completely on the rectangular head.
2. If prints are bad, or if there are horizontal white lines in place of ink on the paper the Ink Cartridge nozzles partially blocked.
Cartridge Cleaning using Software
Using Cleaning option in Maintainance can rid you of minor clogs in the cartridge.
Deep cleaning is a sheer waste of ink, and is best avoided.
Manual Cleaning involves using IPA or warm to boiling hot water to unclogg and loosen up dried ink from the head of the cartridge nozzles. A clean head leaves a neat ink train on a soft tissue. Cleaning involves :-
1. Using a clean soft tissue dabbed in Iso Propyl Alcohol , to wipe the head.
2. Using a clean soft tissue dabbed in warm water, to wipe the head.
3. Soaking the ink cartridge head in warm water for 2 to 5 minutes.
4. Soaking a clogged ink cartridge head in hot water for 2 to 5 minutes.
4. Soaking a undetectable ink cartridge head in boiling hot water for 3 minutes or using steam to clean them up .
6. Opening a dead cartridge and cleaning it up with hot water and then resealing it.
You can spray the clogged head with hot water too and wipe with cotton or a soft dry paper tissue.
Chk out :
Dont let the empty cartridge run dry, keep empty cartridge airtight by putting a tape over the head or cling wrapping them, emulate how new cartridges have orange tape.
Refill from a good/reputed re-filler or he will damage the cartridge. Else buy a kit with ink specific to your printer, 5 /10 cc syringes and needles and a universal suction adapter to remove air bubbles.
DIY refilling is messy business. Black is easy, Color cartridges are more difficult to refill. Clean the cartridge head before a refill.

I have this fashion stitch sewing machine that my sister insisted on buying, but it turns out that she never intended to stitch but to use me as her unofficial alterer or tailor.
Even after a couple of yrs, i didnt quite know how to properly use it and the only thing i did was to use the straight and zigzag stitch. So thanks to you tube i finally figured out how to stitch on a sewing machine. Now i got to figure out how to teach her to stitch, and maybe this post will.
I have been taken for a ride by the Whirlpool Service guys n number of times as most likely than not you have too. If you figure out the system u could diy repair or make sure that the service man is qualified or some anadi sent by the service co. In India the multi-meter is an alien object to the repair guy. No wonder we face shoddy service.
The 7 year contract of my Whirlpool FF 350 L Elite model , imported from brazil, REFRIGERATOR BRASTEMP BRM35A 350 FROST FREE just ran out, and the way the service standards of whirlpool are, continuity tester in hand i bravely decided on doing the faultfinding myself. Actually most FF fridges are similar and the same rules apply to most fridges..
Homosexual intercourse was a criminal offence until 2009 under Section 377 of the Indian Penal Code, 1860 … A british legacy.
Sec 377 was a great source of underhand revenue for some crooked cops, and naturally a major tool for intimidation and harassment of the rainbow community.
This law was struck down by the 2009 Delhi High Court decision Naz Foundation v. Govt. of NCT of Delhi, which found Section 377 and other legal prohibitions against same-sex conduct to be in direct violation of fundamental rights provided by the Indian Constitution.
We even laugh at
No one except the deobandis, the church, the BJP and some devout followers that considered gay sex as a disease made some noise.
The health minister Ghulam Nabi Azad was one of the loudest
LGBT s come out all guns blazing in the media against his outrageous statement and Congress calculates the quantum of loss / error of judgement and makes him explain his statement.
Come 2012 election time: 16 February 2012, the Supreme Court, during a hearing of a bunch of appeals filed against decriminalization of gay sex, observed that homosexuality should be seen in the context of changing society as many things which were earlier unacceptable have become acceptable with passage of time.
The Sonia congress upa stand?
This is during the UP elections when its senior politicians have made a mockery of the law and of the Election Commission to draw in the Muslim vote in UP.Muslims are a huge vote bank … a Majority block of votes that can make or break a party’s fortunes.
Come the last day of UP Elections, the Sonia congress does a royal about turn in the Courts, to which the court reacted
“Don’t make (a) mockery of the system. ASG Malhotra has already argued the case for more than three hours. Don’t waste the court’s time,” the bench said.
“You do not have to argue fresh … You are appearing for health ministry. Tomorrow someone may say that Jain was not authorised to argue the case. We do not want to embarrass you,” the bench said.
Looks like Sonia Congress UPA is Duplicitous , and no less communal. It is worried about the backlash of its Muslim vote bank when it comes to elections.
If BJP has their VHP then Congress has their Deobandis.. no wonder its stand changes in sync with the election calander..
The man who did everything straight from his heart, be it singing or talking politics.. Jagjit Singh will always be remembered not only for his gazals but also as an incredible human being.
