Coleman Heatpump won't restart

Hello everyone, my first post in your forum,
We in the northeast just had a Major Blizzard! This morning I went to clear the snow around the house and found the heatpump violently shaking up and down on its brackets to the foundation. I noticed ice on the fan blades and racket noise from the housing. It reminded me of car engine run-on the fan spun slowly and perhaps it was doing so by the rocking motion of the whole chassis. I immediately turned the unit off. Later all the ice and snow were melted off. I tried to restart but the Tstat flashed emergency heat and a 02 code in the led temp display. I heating with oil and its going down to -20 celsius so it would not be missed. Any suggestions as to starting it or do I need a tech?

Follow up to to Coleman won't restart

Thank you for the reply, I presume you used industry
shorthand in your answer. I will get schematic attempt
to observe conditon of components. Does it really mean
the pump is dry (lost charge) furthermore, last spring the
pump did not work it fried some components ie wires
were shorted out. It may not worked for awhile since
I wanted to test A/c in March before any heatwave
occurred and service people were extremely busy. I now
pay more attention to it !

Update Pump has resumed operation!

Today in the northeast we are experiencing above normal
weather 7 C plus rain. Emergency heat ceased to function
on oil burner prompting checklist proceedures. Apparently
resetting furnace reset the thermostat. Pump started to
work normally. Just before this oil furnace was acting inter-
mittantly and not at all. Cold air was being circulated by fan.
Almost as though it did not know there was no heat.
Thank you again , I will review all information as to prevent
itive proceedures and maintenance .
