Why?Most four strokes do like to get a little warm when just idling. But if it's real bad check your radiator fluid (of course) make sure its filled to the top of the fins, not to much over or it'll be overfilled. Then also look for air leaks. If there is a hole in your rubber piece leading from your air filter to your carburetor or anywhere where possible air can get into (and isnt suppose to) that'll heat up your engine to. If it tends to rev weirdly, like after twisting the throttle doesn't drop back down to idle quickly, then theres probably an air leak. One other thing is, check your jetting, if its set too lean then it could overheat to. this mainly is cause by after market parts (pipe mainly). To see if it's too lean, your muffler will have a sort of whiteish look on the inside of it. I'm not sure on what else to check. But if you do have an after market pipe, check with the makers to see if they have a recommended jet settings.,,,

Honda shadow vt1100c 1986 idile to low after running awhile


There's an idle adjustment screw. The bike runs faster when cold because the fuel\air adjustment is richer on a cold engine. When the bike warms up, the fuel becomes more lean in mixture because the heat causes the fuel to expand, i.e., less molecules of fuel to the firing sequence of the piston. When the bike is warmed up, after say ten minutes, the heat causes a leaner mixture, so adjust the idle on a hot engine (about 1000 rpm more or less). The bike will idle faster when cold, then drop rpm's as the engine warms up. Good luck

Oscillating drum sander runs a few minutes and stops


This usually occurs if the motor is overheating and the internal circuit breaker is tripping. After it cools down, it self resets. This can be caused by bad bearings or parts dragging the motor down, making it work hard enough to over heat and trip the breaker. If you are running it on an extension cord or circuit that isn't able to provide it with the amps it needs the motor will overheat and trip the breaker also.

Air compressor starts and then shuts off


Do you mean it runs for 1 or 2 seconds and stops or it runs for minutes and stops? If it never really starts (runs for a second or less) then it is probably a capacitor start motor and the capacity has gone bad.

If it runs for minutes or more and then stops and subsequently restarts when it has cooled then the thermal overload switch is turning it off when the motor overheats. If the unit is not all that old, hasn't been run particularly hard and you have this problem every time you turn it on when it is just pumping up, (which is to say, there is no good reason for the motor to be overheated) then the thermal overheat switch is probably defective.

If the compressor is being run hard when this happens, then the unit is being overheated from heavier use than for which it was designed. If the interior of the compressor motor has a coating of saw dust or dust, it acts like an insulator and results in the motor heating more quickly than it should under normal circumstances. Also, if it is being used in a hot environment it will likewise have trouble cooling.

So, if it really doesn't run at all, it is probably the motor starting capacitor. If it happens when the compressor isn't really hot, then the thermal over-temperature switch is probably defective. If it gets genuinely hot, but without being run hard, then the motor might need to be cleaned because it is not cooling properly. If it happens when it is hot and it is hot because it has been run hard, then either don't run it as hard, cool it better or get a bigger compressor. If it is clean inside, not being run hard but still overheats, then I would look at a malfunction in the compressor portion of the unit having more friction than it should (bearings lubricated?) thus requiring more horsepower to run the compressor than the motor is designed to generate and results in overheating. Low voltage can also do the same.

Overheats. runs fine when idiling.holding the fan off, and a/c on still cant make it overheat but once driving for 5 mins starts to overheat. replaced thermostat, water pump looks to be fine. cleaned rad....


Water pump. The impeller will slip on the shaft. As you said runs fine at idle, but when you run it harder the impeller doesn't spin fast enough (slips). Causing it to over heat. replaced to many for this problem. Also The pumps that have the metal impellers will be tight when cold, don't let this fool you. when they heat up they slip.

Overheats when idiling and overheats , cools down , overheats when driving. Have replaced the thermostat but is still doing the same thing. There are no apparent waterleaks. No water in the oil and runs...


When the car is completely cool,check the electric fan(s) for smooth rotation.

Clean/check/change the thermo sensor,contact and wire.

Excavate air pocket in coolant system / check for head gasket leak

This test will kill two birds with one stone.

===

MAKE SURE THE COOLANT SYSTEM and ENGINE IS COLD!

RAN THIS TEST IN A WELL VENTILATED AREA ONLY!

You will spill some coolant during this air pocket purge test.......BE KIND TO THE ENVIRONMENT and ANIMAL please clean up after the test!

===

Put the front end on a pair of ramp or park your car on a VERY STEEP HILL (radiator facing top of the hill) .

Top of the coolant reserve tank

Let it ran for 10-15 minutes.

Monitor for air pockets escaping from coolant reserve tank.

Small amount of bubbles is OK at 1-5 minute mark

After the thermostat open up (after 195 F warm up) at
5-12 minute mark or after high idle you should see less bubbles.

If you do not see any in rush of bubbles then your thermostat may be partially stuck or rusted badly inside the thermostat hosing.

Give the thermostat host few gentle taps.

If you see larger bubbles surfacing after 15 minutes then should do a hydrocarbon (HC) dye test to test for potential head gasket leak.

Let engine cold down and top off coolant reserve tank.

Start monitor for coolant lost

===

A coolant flush is require every 2 years or 24,000 miles.

I recommend the thermostat that has a relief pop-let to reduce the change of burst radiator and coolant hoses.

Make sure you get a new thermostat gasket,black RTV and fresh coolant for the job.

Over heating triumph sprite motor cycle 955cc


Sounds like an airlock. When it fell over an air bubble would've gone to the highest point of the cooling system, & when you picked it back up the air gets trapped, if it gets trapped near the thermostat it will send the computer a false reading & fans wont turn on causing an overheat. Give the cooling system a flush. Remove lowest cooling system hose you can find I think its the water pump hose, & remove the radiator cap all the coolant will drain. Put your garden hose in the radiator turn it on & start your bike, run the hose through it for about ten minutes or untill the water coming out of the hose you removed runs clear then shut the bike off. Put the water pump hose back on, clamp it up, & fill the radiator 50/50 water/glycol. Leave the radiator cap off start the bike & get it to normal operating temperature, as it warms up air will rise to the radiator cap & the coolant level will drop just top it up accordingly. Once the bikes warmed up & bubbles stop rising,  put the cap back on & take it for a ride. Hope this helps!

Air handler only blows air for 3-5 minutes before shut off & not cycling frequently


Sounds like it could be a very weak run capacitor on the blower motor. Run capacitors are sized specifically to the needs of the motor. When a run cap gets weak, the motor trys to compensate for it by drawing more power. More power draw = more heat in the motor, then the motor will overheat and shut off to protect itself. When the motor cools off it will automatically restart and run until it overheats again. Keep in mind that I am a technician that normally diagnoses equipment in a hands on manner. There are many practices and concepts that transcend all air conditioning systems but it is a constantly evolving industry. I live in south eastern WA and I don't see Amana units except as window units. It is possible to have something else causing this problem (faulty thermostat, failing thermal relay(if used), problem with electronic controls(if used)) there are a lot of potential variables

When starting, hear a noise like if the motor has problem rolling. The dryer works but stops during the cycle. Smeling heating after a while. And few minutes later, restarts and works, and stops...


sounds like your motor is on the way out. Hard to start-- when it does go it eventually overheats---- wont restart till cools down. sounds like a motor going bad
