Hello everyone!
If everyone coud give me the correct procedure to extract the protection device at an compressor Tecumseh TAG 5561E, I would be very grateful.
I thing at Murphy's Constant "Matter will be damaged in proportion to its value"

According to Tecumseh....


A. Internal Thermal Protectors


Internal thermal protectors are completely internal and tamper-proof. They cannot be by-passed.

Single Phase Motor Thermal Protectors




Internal thermal protectors detect excess heat and/or current draw. They are located in the following single phase motors: AB, AW, AH, AV, and AG.
3-Phase Motor Thermal Protectors




The 31HM and 32HM on-winding motor protectors are 3-phase line break, automatic reset devices wired in series with each phase at the neutral point

and mounted on the windings. They are used in AB, AG, AV, and AN models.
So they do not have instructions available for this type of repair.

Are you doing a motor rewind?

The compressor is quite new, it was stopped in winter (system is a split one), and now it refuse to start. I tought that the protection device is mounted in the terminal box and i can replace it.

Think its internal on these if i rember right, ImI used the tag on smaller splits. If the unit is short of gas it will trip on this. Or possible discharge reeds failed inside comp. :cool:

Hi, peter11
I think u must buy a new comp. if the internal protector is surely broken, cause it's more expensive to replace an internal protctor than to buy a newone..;)

Have you checked the continuity of the motor windings ?

A Tecumseh has no internal protection like a Danfoss or a Maneurop.
It's protected outside via a clixon.
Dan's advice wasruight, have you measured windings: main winding, start winding and the sum of both?

Thanks "all my hard", I did not know what this forum realy is.
I measured the resistance, it is infinite, in others words,there is no continuity at all 3 windings.T1-T2;T1-T3:T2-T3. That is why I was thinking at the neutral point. I checked the voltage, it is perfect simetricaly,Ok. Surely the amperage is zero! (measured for certitude).The pressure, suction and head is (are) the same, in concordance with temperature-refrigerant.
Certainly the compresor is triped

I don't think so. :p I found the information of TAG 5561E as following:
Displacement : 112.5 cm³
Net weight : 44.5 Kg
Oil charge : 1960 cm³
Oil type : Minérale / Mineral
Expansion device :Capillary/Exp° valve
Cooling : Forced
Windings resistances at 20° C
Phases1,2,3. / Phase Nr 1,2,3 : 3.18 Ohms
nom. / Rated current RLA : 9 / 9.9 A
max. / Max current : 15 / 15 A
Start current LRA : 51 / 53 A
Electrical equipment : TRI
Overload: Interne / Internal
According to petre11's measuring, I regard the main winding may be burned out for overload or other reason.

May I ask, where did you find this information?
We're installing almost every week such a compressors and this is the first time I hear of an internal protection.

Dear Sirs!
Thank you very much! The specifications are very helpful. I concluded that the protector is internal, if you have the time to open the attach. you will see that it is a Klixon based device not an electronical-sophisticated one. I am much obliged, the first answer began with this ideea written in red.

Best regards! petre11
