Ptc relay reasons for frequently damaging the relay

Question edited for a lot more clarity.

Step 1:
It's most likely the PTC (Positive Temperature Compensated) start relay that turns the compressor on and off. The manufacturer has replaced part number P6R8MC with part number 6R8MG for this PTC start relay. Order part number 6R8MG, it cost less than $20 from AppliancePartsPro
First, unplug the wine cooler and take off the back panel. The back panel is held into place with several philips head screws.

Step 2:
Locate the compressor. You'll find the compressor in the bottom left corner of the VT-60 as viewed from the back. You will see copper tubes coming out of the compressor. These tubes carry the compressed refrigerant to the evaporator assembly. Be careful not to crimp or damage the copper tubing.
Step 3:
Find the black plastic cover to the left of the compressor. This cover is held into place with one philips head screw. Remove the screw and remove the cover to find the PTC start relay.
Step 4:
The relay is connected to the compressor by a single blade connector and two pins which protrude from the compressor. Remove the blade connector and pull the PTC relay to the left, sliding it off the pins attached to the compressor.

Step 5:
Slide the relay on the connector pins, reattach the blade connector, reattach the black pastic cover over the relay, reattach the back panel onto the VT-60 and you're done.

depending on the model and the part # of the ptc overload relay will tell you how to wire it back as was,on some ptc O/L's there are spaces on the component where you just plug it on piggyback to this ptc,if not then all you do is wire the capacitor in parallel to the 2 power pins on the compressor,the cap doesn't actually start or run the units compressor,its there to help suppress the arcs on the relay when it starts,the compressor will operate without this capacitor

Hi and welcome to FixYa, I am Kelly.
The compressor is attempting to start but not rotating. The click you hearing is the compressor thermal overload cycling. The start cycle shoud repeat about every 4 minutes initiating a start cycle for 15 to 40 seconds and then repeat again in approximately 4 - 6 minutes.
When a compressor will not start there can be many reasons:
1. The PTC start relay has failed
2. The run capcitor has failed
3. The compressor rotor is locked from an internal failure.
4. Wiring at the compressor connection has been hot and does not provide enough startig current.

As of Jan 2009 oster is no longer able to support their mini-frigde units as the manufacturer filed bankruptcy. They direct you to http://www.apwagner.com for parts. I check the apwagner site and the do not list any oster models.

I will say that you can hand carry the PTC relay, overload and capacitor to most any appliace parts sourc and find a replacement.

I would do a resistance check of the the compressor terminals to the case of the compressor looking for shorts to the body of the compressor (none allowed)
I would then replace the PTC Relay and {run capacitor if used} If it still did not start then the compressor is locked. A new compressor, coolant, service call and labor would be at least 2 times what the unit cost new. ( What stinks about buying a new PTC relay and capacitor and then finding out the compressor is locked up; means your out the cost of the parts just to troubleshoot. The troubleshooting process forces us to change the PTC relay capacitor and often the Kixon Thermal overload protector just to end up with the compressor is locked diagnosis. There is no other way sadly.

no there is reset,but,the ptc overload relay plugged into the compressor is bad,purchase a new replacement ptc overload relay and plug in into the compressor and it will again cool properly

replace the ptc overload relay combination plugged into the compressors side in the rear area of the units base with an exact replacement ptc overload relay,just be sure to unplug the unit from the wall first,it merely unplugs out of 3 connections on the compressor after removing the spring wire that holds it in place on the compressor

Power off i.e unplugged
Open the back
Remove retaining clip on wiring side of compressor plastic cover.
NOTE wiring connections to terminals on the OLD relay. 1, 2 4 4 ect... make a simple wite color to terminal number sketch.
PULL off PTC relay WITH terminals by pulling HORIZONTALLY (Usually to the left / 9 O'clock position)
NOTE the thermal overload comes off WITH the PTC relay.
Remove wire from Thermal overload terminal and transfer the thermal overload to the new PTC relay.
Slide NEW PTC relay onto compressor terminals
Transfer remaining wires from OLD PTC to the correct terminal on the new PTC relay.

TEST compressor start before installing cover... PLUG in unit

After the test unplug the unit... reinstall the plastic cover and wire clip.

Reinstall back panel

Return unit to service.

NOTE the thermal overload will s akl

Some of the PTC relays just give out for no apparent reason. (the brown ones more than any other) But in your case you can see physical signs of overheating. I would suspect the compressor has seized up, or has a shorted winding.

This is for a Kenmore PTC relay that I just pulled from my fridge. It dosn't have an ice maker. Hope this helps.
