Question about Hitachi EC12 Portable Electric 2hp Air Compressor, Oil Lubricated

1 Answer

Compressor attempts to run, trips overload

My compressor is almost brand new in hours however when I try to run it ,it makes a few revolutions, stops, and trips the built in overload switch. I do not use an extension cord so I don't believe voltage drop to be an issue.

    I have checked the oil and I believe it to be full however I am at work and I will re-check when I get home.

Do you have the facility to top up the oil level on the compressor

If so you may find that the low oil sensor is kicking in and trying to prevent you from running the machine dry.

    Just had a thought

    Most comressors have a one way valve in the line leading from the motor to the receiver tank.

    This stops the pressure in the receiver tank from blowing back into the compressor motor when it is on full pressure and the motor is stopped by the pressure switch

    If that is sticking the compressor will be trying to pump air to the tank but will only be able to fill the short hose connection until the motor stalls.

    We had lots of problems with an Enotts valve that did exactly that

    Try disconnecting the supply hose and allow the motor to run free

Model ffu213caw1: my freezer stopped cooling recently.there is power to the uniti hear a small click down near the compressor like it is trying to start and then it stops.compressor is warm to the touch...


Compressor is bad the clicking noise is the Start Relay/Overload is kicking on and off. compressor is warm because it's trying to start but can't Frigidaire is known for bad compressors. I don't think the Start Relay/Overload is bad because the compressor gets warm.

Stop working. stop running. where is the reset button? where is the overload?


It will be very diffilcult for even the most experienced technician to troubleshoot your refirgerator with so little information. No make and model number, no infor on how old it is...therefore start with the basics:

Verify it has power (does the interior light(s) come on?

If so, most refrigerators DO NOT have a reset button. The motor overloads reset when they cool off. If your unit has power and will not start after left alone (unplugged) for a few hours, then either the thermostat controls (most likely), a part of the thermostat controls (some controls use mutilple sensors and control relays), the overload on the compressor is bad or the compressor itself is bad. If the condenser fan runs but the compressor does not...I would suspect a problem with the compressor or it's electricals. If nothing starts except lights...I would suspect the temperature control. Good-luck.

Fridge has stopped working/getting cold


check the relay, the clicking noise is your overload tripping out on overload, the run winding of the compressor are not coming on line, if your relay is good, the ohm out your compressor.

Help w/ Refrigerator Compressor Overheating?


I had a similar problem yesterday (Maytag side by side unit 5 years old, however this apply to most brands). All operation seems normal other then that the refrigerator was not cooling, the air that was blowing inside the refrigerator was room temperature and not cold air. The compressor was also very hot to touch (could not touch it for more then 1-2 seconds) and didn't buzz or hum as in standard operation. I also heard few clicks from the compressor every time I plugged / unplugged the AC to the fridge. Replaced the overload/ relay device with a new one I got at a local appliance parts distributor ($30) and MAGIC. The unit went back to work as soon as I plugged the AC power. The relay/overload unit is on the side of the compressor and that?s where the electric wires are attached to. The unit turns the compressor on and off. The unit is attached to the compressor side with an "electric outlet" like three holes and three prongs. It might be held tight so you can pry gently (between the unit and the compressor body) with a screwdriver. Once pulled out, release the wires connectors that are attached to the relay/ overload unit. You might need to use pliers as they are tight fit. If unit smells like burnt or if you shake and hear rattle then it?s bad. Find a local appliance parts distributors and call to see if they have part for your model/ type. Remember to unplug AC before starting to work on the fridge and good luck.

The click is not normal. The compressor is not starting and is tripping the overload. There is a chance the start relay on the compressor is shorted, but most likely the compressor will have to be replaced.
Unplug it for several hours until the compressor cools down and then try it again, if it starts up ok when it is cool the compressor is the problem for sure.
If it is less than 5 yrs old the compressor is still covered by warranty and will be replaced free of charge.

Compressor help


If the compressor is real hot, caused by lack of cooling air and the thermal overload is what's tripping try letting it sit for several hours to cool and try again (clean the front lower coils for proper air flow). If that's not it then you likely have a "start device" failure. The kit comes with the overload and starter. Usually this is the problem BUT if you have a "Tecumseh" brand compressor you're toast. Take the back panel off the fridge and look at the compressor, if you have a little sticker on it with an blue indian head... the compressor is locked up (and even a new one is just as junk as this one). But if you have another brand the little white box on the left could be the problem. Unplug the fridge, unplug the little box (starter) and shake it to see if you hear any rattling or if debris falls out... a sure sign the device is bad.
