i got a soleus portable heat & air unit and there's a problem with the heat. i've tried many troubleshooting procedures and am now down to capacitor issues. so here it goes. the cooling part works just fine, but when i turn on the heater, i only get slight warm air from the unit even though the fan runs full. i opened up the unit and the metal grill that is supposed to generate heat is connected to a large capacitor, the same one that the AC unit is connected to. Because the cooling runs fine, does that mean the capacitor is good or are there still doubts that the capacitor could be bad that's...
