Your compressor is locked up. i would try replacing the round start capacitor. you need to check what the exact rating for yours is but I believe one of these two will work for ya. In the meantime do not continue to try to run it, it will kill the compressor.

Why do young child struggle in daily routines?


There are many reasons a young child may struggle with day to day routines. The most common reason is their attention span. Up to the age of 5 years old, a child usually has one minute of attention span per age, so a 2 year old has a two minute attention span, a 4 year old has a 4 minute attention span, and so on and so forth.

The second most common reason is that they are given too much responsibility too soon. While children can help with chores at all ages, the chores need to be age appropriate, so you might give a 2 year old a dust rag to wipe a table with but you wouldn't give them a vacuum cleaner of course.

Another common reason is that children don't get nearly enough sound sleep these days. Infants and toddlers need on average 12-14 hours of sleep a night. Some may be able to get away with as few as 10 hours, and others may need as many as 16 hours of sleep a night. 3-5 year old's need anywhere from 10-13 hours of sleep a night and some need as many as 14 hours of sleep a night, while others can survive on only 9 hours of sleep a night. Older children in the 6-13 range need a minimum of 9 hours a sleep a night, and the average child in that range needs 10-11 hours of sleep. Some get by on as few as 7 hours while others need as many as 12 hours. No child under the age of 13 should be sleeping less than 9 hours a night. If they are, it could be one of the reasons that you struggle with the day to day routine, especially if it's the morning routine.

Other common reasons for a child having a hard time with a day to day routine is the need for a nap, not drinking enough water, too long of a wait between meals or snacks that's causing low blood pressure, and distractions by siblings, video games, etc.

2yrs old. Went thru 3 sets of batteries to get 20 pictures. Dead again. What`s the story?


Sounds like you have a short in the wiring. This is repair shop stuff, or buy a new camera time. Usually, if it is a point and shoot , it is not worth sending for repair as you'll playas much as a new camera is worth. I would look for a new camera, personally. Good luck.

Does not last more than 5 months.Warrenty given only 3months.If this goes on we have to switch to another brand as it destruct our works.We have used more than 10 units.Please advice.


These are probably intended to be used a maximum of 2 hours a day. What are you using them for? If you are using for paint stripping for 4 hours a day they will probably only last a couple months. The more expensive Master ones will last longer but cost a lot more. Harbor Freight tool has these at about $8 and those may last as long as the ones you are using. The motor brushes probably are the failing point. There are a couple brands that use induction motors that don't have brushes but they are less portable.
