12 Volt power to controls but nothing happens
Possible Causes
- Controls might be bad or cooling unit might be bad
Try
- Wire heat element direct to 110 volt source
Pro Tip
The easiest way to pinpoint controls or a bad unit is to wire the heat element directly to a 110 volt source. This bypasses controls. If the cooling unit heats up but still doesn’t cool you might have a bad cooling unit. If you hear a percolating sound the cooling unit is low pressure.
Shipping Damage
The most common type of shipping damage to units is that the pipe is bent out of level. Flip through the photo galleries below to see how to fix this issue on different brands.
Dometic cooling units
In Dometic cooling units make sure fins are level side to side as well as front and back.
Norcold cooling units
Norcold cooling units come with either 1 tab or 2. In the 1 tab models make sure fins are 3 degrees higher on the left side than the right side, but level from front to back. On Norcold models with 2 tabs fins need to be mounted level, not 3 degrees off level.
