Understanding the Difference Between Control Box Panels MPN3229 (98-9070 & 98-7913, 98-8512) and MPN3257
This article explains the functional difference between Myriad parts designed to fit control box panels MPN3229 and MPN3257. It also outlines the Thermo King® reference numbers that each panel replaces.
Overview
Customers sometimes ask why both MPN3229 and MPN3257 reference the same Thermo King® number 98-9070. The short answer is that MPN3229 is the universal replacement for all related Thermo King® numbers and is the only panel that Myriad supplies for this application.
MPN3229
Status: Active
Type: Standard panel control box
MPN3229 is the current and fully supported panel control box. It includes an additional fitting that allows it to replace multiple Thermo King® part numbers without modification.
Replaces the following Thermo King® OEM numbers
-
98-9070
-
98-7913
-
98-8512
This means MPN3229 fits all applications that previously used MPN3257.
MPN3257
Status: Discontinued
MPN3257 was an older version of the control box panel. Myriad no longer supplies this product.
Although it referenced Thermo King® number 98-9070, it did not include the additional fitting found on MPN3229. For this reason, MPN3229 has become the single solution for all compatible units.
Summary
If a customer asks which control box panel they should order, the answer is simple. MPN3229 is the correct and universal replacement for all three Thermo King® numbers, 98-9070, 98-7913 and 98-8512.
It is the only panel required for these applications.
