It's a HOT BOX

Yes, that's right - HOT. We loaded up the fridge before departing to the 49th annual WBCCI International Rally. I placed a temperature logging probe in the bottom rack of the fridge prior to loading. The fridge was running electric before loading and actually was half full before the probe started recording.

Prior to leaving I switched to gas on the fridge. The fridge was full. The freezer was also loaded with things that were already frozen. I had placed a small battery powered fan in the fridge. This fan is very small and does not really circulate much air but it is probably better than nothing.

We got on the road at about 10:00 and drove straight from Reno to Bend, Oregon. We stopped only briefly for dinner at Lakeview, Or at about 4:30.

When we arrived in Bend and opened up the fridge to just check on things we were shocked to feel that the fridge was beyond warm. It was hot. It was warmer than we have ever felt before. I pulled out a hammer and tap on the coils with authority (and perhaps some anger). My thinking is that if the little pilot tube is partially clogged this may help to clear it. Looking at the graph it seems to have helped as the temperature quickly drops with the fridge still partially filled.

The Chart Says it All



Here is what the chart means:
1. Fridge loaded and probe starts recording.
2. Fridge switched to gas and we hit the road.
3. 6:30 p.m. the probe records the highest temperature of the trip - 84 degrees. We drive on not knowing the condition exists.
4. Arrive in Bend and discover the fridge is quite warm. We buy a cooler and unload the most perishable things from the fridge. I bang on the coils.
5. The following day we arrive in Salem at the International. Fridge still not doing so good.

This is what the fridge did during the entire trip...

So now what???

We have been talking about replacing the fridge for some time and now is the time. As of this writing we have ordered a new fridge from our local dealer and have scheduled the install. I would tackle this myself but as we are installing a fridge that is not a direct replacement and will require some modification that I do not feel comfortable dealing with.

About the Probe...

Temp Probe
To record the fridge temperature I purchased a data logging temperature probe from Transcat as a catalog special. The probe I purchased is the EL-USB-1 temperature data logger with a measurement range of -35 to +80C (-31 to +176F). This data logger can store up to 16,382 readings and is supplied with a long-life replaceable lithium battery, allowing the unit to log data continually for at least one year (depending on logging rate and temperature).

The logged data stored in EL-USB-1 is downloaded via the configuration software. Once downloaded data can be graphed, printed or exported to other applications. The data logger configuration software is compatible with Windows 98/2000/XP. CLICK HERE to read all the details about this probe.
