Model No. 8333C876, Serial # 070512361: This unit had been cycling on and off (as it normally does) for 2 days. After being idle for about 30 minutes, it kicked on (fan and compressor) for about 10 seconds then shut down. Now it will not come back on at all. Could the termostat be the problem? If not, what?

    Did you double check that breaker for power didn't trip? Are you hearing anything at all, when you try fan only, or cool is selected, such as a slight "hum" or "click" at ceiling area?

Coleman Mach Model No. 8333C876, Serial number 030508618. I just bought a 2005 Jayco Popup Camper with this unit on top. Both Low and High Fan controls work OK. when I turn the AC knob to High Cool, it will blow cool air. then after about 2 minutes, it seems to power down to a slow blow and my propane alarm begins beeping once per sec. Not sue if its related to the AC unit or the alarm. itself. Hopefully someone can decipher a solution with this description.

How do I reset my KitchenAid Model KUDS35FXSS1

The unit normally has a 1:20 to 1:30 fill cycle with pauses in between while the wash motor starts and stops without running a diagnostic mode this normally happens when the control outputs power to the wash pump motor but the pump doesn't start

Need to know gas mixture

Yours is not a current model and I did not find a manual. The following is an excerpt from a 26cc MightyLite Blower/Vac UT08550/UT08951 "Operator's Manual":
This product is powered by a 2-cycle engine and requires pre-mixing gasoline and 2-cycle lubricant. Pre-mix unleaded gasoline and 2-cycle engine lubricant in a clean 1 gallon container approved for gasoline.
Recommended fuel: This engine is certified to operate on unleaded gasoline intended for automotive use.
Mix Homelite Premium Exact Mix lubricant with gasoline according to the instructions on the package. If Premium Exact Mix lubricant is not available, use a high quality synthetic 2-cycle engine lubricant, mixed at 2.6 oz. per gallon (US).
Do not use automotive lubricant or 2-cycle outboard lubricant.
NOTE: Premium Exact Mix fuel mix will stay fresh up to 30 days. DO NOT mix quantities larger than usable in a 30 day period.
PREMIUM EXACT MIX (50:1)
GasolineLubricant
1 gallon (US) 2.6 oz.
1 Liter 20 cc (20 ml)

If properly adjusted your blower will operate fine on 50:1 regardles of what the manual reads. HTH

I have a Goldstar GHD30 dehumidifer that I bought used last week. It's pulling 20-30 pints of water each day out of my basement so it appears to be working. The compressor only runs for 1-2 minutes at a...

yes cycles should be longer either that or the unit is keeping close to desired humidity. Also the unit is under sized 30 pint is for 400sqft. or 20 by 20 room. humidity should be 30/50 percent check your level desired room temp is 70 degrees but its a basemnt 60 works.

VOLVO S40 SE 2001RPM HIGH

YOU MAY HAVE A IDLE SPEED CONTROL VALVE PROBLEM, CLEAN IT FIRST, THEN DISCONNECT THE BATTERY, FOLLOW THE PROCEDURE I HAVE ATTACHED.

Here is the most common cause of this stall and idle speed issues, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Long washing cycle

sounds like a long time. sounds like it will wear out your dishes before it ever cleans them.
check the manual for cycle times.
could be a bad logic board, too. this happens most often when units are new.
talk to the service center for the unit since its new. they will be able to get right to the problem or send a repairman under warranty.
new units do fail.
good luck
