2012 ford focus window regulator repair notes 2

This is a continuation of my original article and includes videos.


I had first looked at the control module. I don't think it would be possible to trouble shoot this effectively unless you were very determined. I looked for the obvious, bad solder joints, spider nests, corrosion, missing, damaged bits. Here is a good look inside. Mine was fine.


This is an explanation of the regulator together along with a folded view, the way it is inside the door as well as laid out on the bench so it is a bit easier to understand.


An examination of the failed motor. It still worked, went down with help but needed a lot of help to go up. Turns out it was rusty. Very strange considering the condition of the inside of the door. Where did the water come from?


A test of the new motor in the regulator before installation into the door.

As I said earlier, this is not a how-to, but a few notes about my experience, in case it helps you. I did not find much on the web when I had to do mine.

EnerGuide refrigerator test specifications

INDEX to the series

I am trying to find out more about these EnerGuide (Canada) and EnergyGuide (US) labels that are required on all the appliances we buy. Have you noticed that there are American ones and Canadian ones? There are yellow ones and white ones? There are some that have no rating on the label?

I noticed two labels in one freezer top refrigerator with different American and Canadian ratings. Do we test differently?

I decided to read what a manufacturer is told about the labels at Natural Resources Canada (NRCan), that branch of our government that administers the Canadian EnerGuide program.

You can get this document "EnerGuide Labelling Instructions and Labelling Scales for Appliances and Room Air Conditioners" for yourself from NRCan but you have to ask for it.

On page 12, you will find this statement (click to enlarge).

Here is my letter back to NRCan after getting the doc:

Thank you Lakhbir.

I am trying to understand the numbers on appliance labels and the tests that are done to arrive at those numbers. I am trying to relate mine to what I see from my smart meter data.

Do I understand correctly from the EnerGuide Labelling Instructions ... 2014 which you sent that if I want to see how my appliance is tested (ie - how the manufacturer arrives at the energy usage number for that appliance) that I have to buy a CSA specification CAN/CSA-C300-08 in the case of refrigerators/freezers for $155? (for example at the CSA website). Is this spec available on a loan basis?

Is there a repository of manufacturers' submitted test results that is publicly accessible, ideally via the web? Can I ask for a specific appliance's certification test submission?

Is there a newer Energuide Labelling Instructions than 2014?

I am a writer and a concerned individual who wants to explain the labels and the tests. How "real world" are the tests? I am interested in assumptions about household size, median test ambient temperatures and usage assumptions.

It seems there is an alternate American specification and we (Canada) are catching up?

I received the following reply the next day:

Hello George,
The labels that I sent you were for 2016.
Additional information can be found on http://www.nrcan.gc.ca/energy/products/reference/publications/14626.
This is the information available to manufacturers to create labels for their appliances.
We cannot provide you copies of test results as that belong to different manufacturers.
Each appliance has a specific standard and these are listed on the product pages on our website. http://www.nrcan.gc.ca/energy/regulations-codes-standards/6861
If you have any other questions, please contact me.
Regards,
Lakhbir

This seems to be the American standard and test procedure 10 CFR Part 430, Subpart B, Appendix A to Subpart B of Part 430 - Uniform Test Method for Measuring the Energy Consumption of Electric Refrigerators and Electric Refrigerator-Freezers

Minimum energy performance standards (MEPS) at Wikipedia

INDEX to the series

I have been learning about my home electrical usage through my smart meter data and finding it not so smart without some added software. Nevertheless, I have been making use of all this new data and making improvements (reducing the variable portion of my electric bill) while making plans for next steps some of which involve more measurements.

Adding the timers to the water heater, fridge and freezer to move them off my peak rate times was an obvious move but a bit bothersome. The timers don't always work. I had trouble with a wireless type so went with plug in autonomous timers. The cheap Chinese ones I bought on Ebay for $10 each sometimes do not switch as they are supposed to. I went electronic but it would be simpler just to have mechanical timers and cheaper. Try to find three prong versions (properly grounded). The timer for the water heater had to be wired in.

I have been thinking about remote controlled AC sockets. Particularly interested if they monitored the load as well as controlled it, something like the Belkin WeMo.

What if these devices mounted directly in my electrical panel as snap in replacement approved devices that communicate wirelessly? That doesn't exist yet. Maybe with the Internet of Things (IoT)?

Controlling my appliances could be done currently through some type of home automation system, via software, in a browser. That would be nice. I am looking around for suitable systems.

About the monitoring, I still don't have appliance level data from my smart meter or any meaningful breakdown. There are software tools (some of which have their own hardware and sensors) like Plotwatt, Bidgely, Navetas, eyedro and Neurio.

Some, like Plotwatt, are being marketed to the utilities as a service they would provide, whether added to my bill or not, is playing out now in the market. I am looking at my account on-line at Hydro One Networks and I can see many tools to help me understand my electrical usable but no GreenButton links as yet or any appliance level information, just general.

There are systems marketed for the DIY types like TED (The Energy Detective) and OpenEnergyMonitor.

But using my smartmeter is not the only way to understand my house electrical and to monitor my appliances. It might not even be the best or only way. It will probably be some combination of tools that will guide me to what I need to know.

Different tools work different ways. Some plug in between my appliance and the wall. Others involve the installation of a small sensor in my electrical panel.

Of the plug in kind, the Kill A Watt has been popular for a number of years. It measures the energy used at the outlet and stores some totals like kWh per day, week, month, year since plugged in and if you enter rates, it will give you a cost. It does not connect to anything so you can't get the data out of it and when you unplug it resets. Not very useful with tiered rates but the kWh measures could be useful. It is limited to regular plug in 120 VAC appliances up to 1500 watts so you can't use it for a water heater, clothes dryer or airconditioner or a furnace, in fact any of your larger appliances. But still a useful tool. I have had one for years. It does not measure low power very accurately, like below 10 watts.

These and other types of plug in meters may be available at your library http://georgesworkshop.blogspot.ca/2014/12/your-library-has-tools.html

Understanding home electrical use is part of the broad category of Noninvasive Load Monitoring (NILM). Here is good background at Wikipedia https://en.wikipedia.org/wiki/Nonintrusive_load_monitoring
