Dirty coils/filter or low refrigerant will cause the unit to trip out on overload and shut down until the unit resets. Thats what causes the system to cycle in that manner.

The system needs to be cleaned and then the refrigerant charge can be checked properly. You may find it needs refrigerant as well.

You could try replacing the ignition coil. If it's failed, then it may run ok for a few seconds, but as it heats up it fails. Trying to start again immediately will be too soon for the coil to have cooled down. Leave it a few minutes to cool down and it will run again, but only for a few seconds again.
Hope that helps

the defrost cycle happens 1-2 times in 24 hours usually, and lasts 20-30 which time the cooling process starts may or may not hear the sizzle during the 20-30 minutes.if the frezer-freezes and the fresh food section is cold enough its probably o.k.

Dryer will heat when put on 70 minute cycle but will not heat total time. if you put it on 20 minute cycle will not heat at all.

Hi, Some dryers have a cooling cycle that lasts for 20 minutes to cool the drum and its contents so you don't burn yourself when getting clothes out.

alot of machine have a max drying time of 120 minutes 20 of that will be for cooling so 100 mins hot!

the cooling cycle is usually indicated near the end of the dial in a different colour to that of the hot cycle.

Hope this helps.

I will make about 12 3" passes over 3" square

Nothing's wrong with your gun or machine. Your unit has a duty cycle of 20 percent at 90 amps, meaning that it will work (weld) great for 2 straight minutes and then it needs to cool down for 8 minutes. The duty cycle it is measure in 10 minutes lapses.
All you need to do is to let it cool down, and start again. That's all.

Wire will not feed ,I was welding with my weldpak 100 and it just stopped feeding the wire so I shut it down to look at the next day when I tried it the next day the wire fed like it was suppose to until...

Your weldpack 100 has a duty cycle of only 20 t0 30%, meaning that your machine will weld for 2 to 3 minutes and then you need to let it cool down for the 8-7 minutes, then start again.
If the problem continues let me know.

Starts and runs for 15 to 20 minutes then quites. Once it cools down you can re-start and again it will run the same cycle.

this sound as if its seizing. make sure your 2 stroke is the correct mixture. 40:1 is recommended. i use a little more at 30ml/litre of fuel. it smokes a bit more but i would rather it did that than seize up.

No cycle runs longer than 20 minutes and the clothes are still dripping wet when done.

The motor could be overheating and shutting down. Does it stop mid cycle and the timer keep advancing? if so when it stops wait for it to cool down and try starting it again. If it will not start for a few min. then does it is the motor overheating.

Cuts off in warm weather after about 10 miles

Don't rule out fuel pump. Had a 95 do the same, ran great when cool in morning then when it got hot in afternoon, it would quit. Wait 15-20 minutes & go again, sometimes got me home, other times a few more miles until it cooled down again. Luckily I had access to a fuel pressure gauge. Cool in morning had 49 psi, when it quit, 2 psi. Wait 20 minutes, 49 psi again. If you can drive it around until it starts to act up then run into a repair shop for fuel pressure test it will confirm it. If not, they may need it all day to monitor the fuel pressure & confirm it is pump. If your a gambler, change it & fuel filter. One thing I did get was trouble codes indicating a lean mixture, due to starving for fuel. Have you cycled your key to retrieve any codes yet?

The Air conditioner are good only the adjustment of thermostat are the problem, select the thermostat in lower #3 you observe the thermostat will off in such time temperature reach to #3 If you full adjustment the compressor will not off.
