1999 GOLD CONQUEST NOT COOLING - HEAT GUN?

Hello Todd,
Yes a commercial heat gun can be used however you will want to be careful not to let the evaporator get too hot. If there is oil in the evaporator/capillary tube depending on the heat gun you could run the risk of burning the oil (it would have to get pretty hot) or melting the plastic on the back wall or sides. If you do try to heat the evaporator up with a heat gun just heat it up to a fairly even temperature however I would still recommend using the 100 watt light bulb and waiting the full 24 hours after to heating up the evaporator with the heat gun. The last thing you want to do is start that compressor up too early before all the oil has made its way back down. Hope this helps Good luck.

Yes, it will help but make sure you give it 24 hours in the upright position. Also be careful with the heat gun on melting plastic components. You can also add heat on the capillary tube with the heat gun if accessible.
