Question about Heating & Cooling

Open Question

Why is it that BOTH of my Professional series PS78703 purchased new in spring of 2015, now both display and EC?

I removed the plastic shroud, the compressor runs, there is no temperature difference between the compressor discharge or suction lines. Either it has leaked the charge, or the compressor valves have failed open. I do see oil coming from the evaporator (in the form of dust collecting) on both units it appears to be the suction line tube going to the compressor. Is this model number known for manufacturing defects?

Insufficient cooling is a fridge repair job that you can do without the help of a professional. Often the fridge has a frost-free failure, or the compressor is faulty but there are many other reasons for a fridge not cooling properly. Step 1 – Find the Problem
Your first job is to locate the source of the problem. Consider each of the following:
* Gaskets - Make sure the gaskets/seals are not torn and are sealing properly. * Evaporator fan – Make sure it is working. If it is now working you may have a problem with the fan motor. Check for power to the motor and also examine the fan switches around the door (not all fridges have these switches). * Air damper – Sometimes the air damper will not open up to allow the cold air from the freezer part to blow into the fridge section. * Condenser coils – Check to see that the condenser coils don’t have a dust build-up and that the condenser motor is working. * Compressor – Make sure your compressor is working with on and off clicking noises.

How to restring mower

Making the assumption that you are asking how to replace the pull cord on a recoil starter on a vertical power mower engine...??
You must remove the plastic cover in some cases, and the shroud over the top of the engine to gain access to the gizzards of the recoil starter.
That also means in most cases loosening and removing cylinder head bolts, and you MUST use a torque wrench to replace them to the proper tightness, so be prepared.
Once you have the shroud removed, on the underside will be a round reel that is retained by several bent over tabs. You have to straighten at least two of the tabs, and then you can remove the cord reel.
BE CAREFUL, as there is a flat spring inside that will jump out and possibly injure you.
You have to get the correct cord, string it through the handle in place of the old, cut it to the proper length, feed it back through the shroud, and wind it on the reel. Then you have to pre-tension the spring so that the cord will retract after you pull on it.
Once you have the cord routed and fastened to the reel, and captured on the pull handle, you can wind up the spring.
Unless you are VERY handy and have strong hands, I would not recommend you do the repair yourself. The spring must be tensioned, and held in place. It does not want to stay, and will jump out easily.
If you get it tensioned, the cord in place, then the reel must be put back into the shroud and the tabs bent back in place. Then the shroud has to be re-installed on the top of the engine, and the bolts tightened properly.tom

Pullstart cord replacement

If this is like most simple mowers (using briggs & stratton engines and some others) the recoil starter is in an assembly which is spot welded onto a metal cover. You may have to first remove a plastic shroud (which might include the gas tank - which should have a shut-off valve). Then you should be able to remove the metal cover that includes the recoil starter. When you get that off you will see a plastic spool that holds the cord. This spool is probably held in place by a couple of metal tabs that are bent down. Bend those tabs up with pliers. Underneath the spool is a spiral spring that provides the recoil. Take careful note of how this all goes together. Buy a new cord (available by the foot at a hardware store) and wrap it around the plastic spool. Use a piece of tape to hold the end of the new cord above the spool so you can thread it through the hole in the metal housing later. Put the spring and the spool in place, then wind the spool to put tension on the spring - about 3 to 5 turns in the direction that would push the string out through the hole. Once you have the spring "wound up" remove the tape and thread the end of the cord through the hole. Now bend those metal tabs back down. Put the handle on the cord end (or tie a knot) to keep the spring from pulling the end of the cord back through the hole. Reassemble the rest and you are in business.

My Briggs & Stratton 500 Series with model 10T502, Type 0495 B1, and Code 07011 855 failed to start after I cleaned it because the rope/string had no tension on it. What do I need to do to get it...

Does the starter rope rewind? If So and You removed the engine shroud you have to be sure the Pull Starter lines up with the flywheel nut. If the rope does not rewind the return spring is broken so you have to get a spring and remove the shroud and install it. I would take the shroud off and with me to get the spring and the place may install it for you. Bolt the shroud back on and you should be in business.

Where is the digital thermometer located that is displayed on the rear view mirror in a 2000 gmc sierra?

The ambient air temp sensor is behind the front grill in front of the radiator. Remove the plastic shroud on top of the radiator to get to the sensor. It only took about 15 minutes. I believe there are 4 plastic pins/clips and 2 bolts holding the shroud on.

Losse antena

Did you purchase this unit new? If not, someone may have taken the unit apart and lost a small spring out of the antenna assembly. If you place the unit, display side down, with the antenna hinge away from you, there are two small phillips head screws on the right side. If you remove these screws, a small plastic endcap for the antenna assembly will come loose and the antenna can be removed. Where the endcap and the antenna are hinged together, there should be a small spring that puts tension on the antenna. If the spring is missing, the antenna will not remain in position.
