Customer stated hi limit tripping. Inspected unit and doesn't seem to be over heating. Relay not sticking so hi limit tripping early. Will order hi limit and return. 10/9/19 Removed bottom of unit. Removed faulty hi limit and cover plate. Installed new hi limit and mounted capillary bulb with spacer and mounting plate. Put components back together and tested. Unit heated to temp normally. Okay at this time.
